Systemic Patterns

attribution_drift: Multiple claims cite findings to sources that do not contain them or attribute them to the wrong authors. Claim 8 attributes the .497 correlation to Loschelder & Trotschel when it is from Guthrie & Orr (2006). Claim 9 attributes a paper to 'Loschelder et al.' when the actual authors are Maaravi & Levy. Claim 16 attributes a procedural fairness finding to the De Dreu 2000 meta-analysis when it comes from a later experimental study. Claim 25 conflates findings from three different papers into one cited study.
source_conflation: Two distinct Van Kleef et al. 2004 JPSP papers are conflated into one. The cited paper (PubMed 14717628) is about the interpersonal effects of anger and happiness via tracking. A separate 2004 paper (PubMed 15491275) is about motivated information processing and tests power, time pressure, and cognitive closure as moderators. The document presents both papers' findings under one citation.
date_errors: Claim 17 states '2022 literature review' but the paper was published in 2021. The citation link text says 'Cambridge Core, 2020' which is also incorrect.
one_sided_evidence: The document consistently omits boundary conditions and caveats present in the source material. Phantom anchors increase perceptions of manipulativeness (omitted from claim 11). Bowles et al. found female evaluators also penalized women negotiators (oversimplified in claim 32). Recalde & Vesterlund note unintended consequences of interventions (omitted from claim 34). Logrolling offers were not perceived as more attractive despite being more efficient (omitted from claim 20).

Research consistently shows that higher aspirations produce better outcomes, provided they remain justifiable.
finding Section 1, Aspiration Point concept card Cited: Harvard PON preparation checklist
Negotiation Preparation Checklist - Harvard PON
Details

The Harvard PON preparation checklist defines aspiration point as 'the ambitious, but not outrageous, goal that I'd like to reach' but does NOT state that higher aspirations produce better outcomes. This is a well-established finding in negotiation research (e.g., Galinsky, Mussweiler, & Medvec, 2002), but the CITED SOURCE does not support it. The claim may be true but cannot be verified against the given citation.

parties' initial aspirations and expectations before bargaining have nearly the same impact on the final outcome as everything they do and say during the negotiation itself
finding Section 1, paragraph 1 Cited: Harvard PON preparation checklist
Negotiation Preparation Checklist - Harvard PON
Details

The Harvard PON page emphasizes that failing to prepare is the biggest mistake, and defines aspiration point as a checklist item. However, it does NOT make the specific quantitative comparison that aspirations have 'nearly the same impact as everything they do and say during the negotiation.' This is a significant inflation of what the source actually says. The source says preparation matters; the document claims a near-equal weighting that the source does not support.

Source quote:
Without a doubt, the biggest mistake negotiators make — and one that happens far more often than we'd like to admit — is failing to prepare thoroughly.
Missing context: The source discusses preparation importance generally. The specific quantitative comparison ('nearly the same impact') is not found in the cited source and may be fabricated or drawn from a different, uncited source.

Anchoring, Information, Expertise, and Negotiation: New Insights from Meta-Analysis (Guthrie & Orr, 2006)
Details

The .497 correlation is real, but it comes from Guthrie & Orr (2006), NOT from Loschelder & Trotschel. The document cites the NCMR paper 'Toward a Process Model of First Offers and Anchoring in Negotiations' by Loschelder & Trotschel, which likely CITES the .497 figure from Guthrie & Orr. The document says 'A meta-study reported' implying the cited paper IS the meta-study — but it is not. The actual meta-study author and the cited paper author are different.

Source quote:
Orr and Guthrie (2006) reported a correlation of .497 between initial offers and final negotiation outcomes in a meta-study of 16 research papers.
Contradicting evidence: A more recent meta-analysis (2025, ScienceDirect) of 374 effects from 90 studies (N=16,334) provides updated estimates of the first-offer effect.
Missing context: The .497 correlation is from Guthrie & Orr (2006), not the cited Loschelder & Trotschel paper. This also represents a meta-analysis of only 16 papers.

When your anchor sinks your boat: Information asymmetry in distributive negotiations (Maaravi & Levy)
Details

The finding about information asymmetry disadvantaging first movers is accurately described and supported by the linked source. However, the document attributes this to 'Loschelder et al.' while the actual paper at the linked URL is by Yossi Maaravi and Aharon Levy. This is a clear author misattribution — the link is correct but the displayed author name is wrong.

The De Dreu et al. 2000 JPSP meta-analysis abstract does NOT mention procedural fairness. This finding comes from a SEPARATE study — likely Beersma & De Dreu (published in Social Justice Research), which is an experimental test that built on the meta-analysis. The document presents this as a finding of the same meta-analysis, which is a misattribution. The finding is real but attributed to the wrong paper.

Multiple problems: (1) The document says '2022 literature review' but the paper was published in 2021 (online Feb 2021). (2) The link text says 'Cambridge Core, 2020' — also wrong. (3) The paper is described as a 'literature review' but it's actually a 'comparative study of the USA and Italy' — a narrower empirical study, not a broad literature review. (4) The Western-perspective point is supported, but the characterization of the source type and date are both incorrect.

Source quote:

Concessions are reciprocated — negotiators who receive large concessions tend to offer large concessions in return.
finding Section 4, Concession Strategy list item 2 Cited: Judgment & Decision Making, Cambridge
Accounting for Reciprocity in Negotiation and Social Exchange (Mislin, Boumgarden, Jang & Bottom, JDM)
Details

The cited paper by Mislin et al. is about relational accounting — how prior exchange history shapes negotiation behavior through emotional responses. It is NOT about simple within-negotiation concession reciprocity ('you concede, I concede back'). The paper studies cross-negotiation reciprocity based on prior profitable/unprofitable exchanges. The concept of concession reciprocity IS well-established in negotiation research (Putnam & Jones, 1982; Pruitt, 1981), but this specific citation does not support the stated claim.

Source quote:
Prior profitable exchanges generated affection toward counterparts, leading to lower initial demands and more generous negotiating positions. Prior unprofitable exchanges triggered disaffection, resulting in higher initial demands.
Missing context: The cited paper is about relational accounting across exchanges, not simple concession-for-concession reciprocity within a single negotiation.

The interpersonal effects of emotions in negotiations: a motivated information processing approach (Van Kleef, De Dreu & Manstead, 2004b, JPSP Vol 87 No 4)
Details

The document presents three moderating conditions (low power, low time pressure, authenticity) as part of the same 2004 study cited at PubMed 14717628. However: (1) Power and time pressure are from a DIFFERENT 2004 paper (JPSP Vol 87, PubMed 15491275) by the same authors. (2) Perceived authenticity is from Tng & Au (2014, Negotiation Journal), published a decade later. The document conflates findings from at least three different papers into a single table row attributed to one study.

Source quote:
participants were only affected by the other's emotion under low rather than high time pressure... Negotiators were only influenced by their opponent's emotion if they had low (rather than high) power.
Missing context: These three conditions come from at least three different papers: (1) PubMed 14717628 (the cited 2004a paper) does not test power, time pressure, or authenticity; (2) PubMed 15491275 (Van Kleef 2004b) tests power and time pressure; (3) Tng & Au 2014 tests authenticity.

The document directly cites several Harvard PON 'daily' articles (claims 1, 2, 3, 11), which are editorial/educational content written by PON staff — not peer-reviewed papers. It also cites Wikipedia (claim 12) and institutional pages (UC Davis ADVANCE, Harvard Kennedy School). While the underlying research IS peer-reviewed, several of the document's DIRECT citations link to non-peer-reviewed editorial content. The footer's claim is dubious — the foundation sources include reputable editorial content that functions similarly to expert blog posts.

Contradicting evidence: The document cites Harvard PON daily articles, Wikipedia, UC Davis ADVANCE, and Harvard Kennedy School institutional pages — none of which are peer-reviewed journals.

Negotiators who opened with logrolling offers reached more efficient agreements.
finding Section 4, Logrolling list item 1 Cited: Moran & Ritov, ResearchGate
Initial Perceptions in Negotiations: Evaluation and Response to 'Logrolling' Offers (Moran & Ritov, 2002, J. Behavioral Decision Making)
Details

The finding that logrolling offers led to more efficient (higher combined profit) agreements is confirmed. However, the document omits important context: logrolling offers were NOT judged as more attractive than distributive offers, and they did NOT reduce the fixed-pie assumption. The efficiency gain operated through within-issue anchoring, not through changing attitudes or perceptions.

Source quote:
initial offers did establish within-issue anchors: counter-offers were affected by the specific composition of the initial offers beyond the effect of their overall value. This anchoring process resulted in logrolling offers yielding a higher profit for their initiator, as well as higher combined profits for both parties.
Contradicting evidence: Logrolling offers were not perceived as more attractive and did not reduce fixed-pie bias.
Missing context: The mechanism was within-issue anchoring, not attitude change. Logrolling offers were not perceived more favorably.

Anger extracts concessions from low-power opponents but not from high-power opponents, who may retaliate.
finding Section 5, Critical Moderators item 2 Cited: Van Kleef et al., 2006 (Wiley EJSP)
Power and emotion in negotiation (Van Kleef, De Dreu, Pietroni & Manstead, 2006, EJSP)
Details

The core finding about power moderating anger's effect is confirmed: low-power opponents concede more, high-power opponents are unaffected. However, the document says high-power opponents 'may retaliate' — the paper says anger 'triggered anger' in high-power opponents and 'reduced the likelihood of settlement,' which is not exactly 'retaliation.' The document overstates by implying active retaliatory behavior.

Source quote:
only negotiators who had few alternatives (low power) conceded more to an angry opponent... participants who had ample alternatives (high power) were unaffected. When observers had a strong position, the other's anger expressions triggered anger in the observing party, and thereby reduced the likelihood of settlement.
Missing context: The paper says high-power opponents' anger was triggered and settlement likelihood decreased — not that they actively 'retaliated.'

Bowles, Babcock & Lai (2007) found that male evaluators penalized women more than men for attempting to negotiate higher compensation.
finding Section 6, Updated Evidence item 2 Cited: Bowles et al., 2007 (OBHDP, ScienceDirect)
Social incentives for gender differences in the propensity to initiate negotiations (Bowles, Babcock & Lai, 2007, OBHDP)
Details

The paper confirms social backlash against women who negotiate. However, the document says 'male evaluators penalized women more than men' which oversimplifies: in written transcripts, BOTH male AND female evaluators penalized women. In video assessment, male evaluators specifically penalized women while female evaluators penalized everyone equally. The document's focus on 'male evaluators' omits that female evaluators also contributed to the backlash in some conditions.

Source quote:
When assessing candidates through videotapes, female evaluators penalized both male and female candidates equally for negotiating whereas male evaluators only penalized women candidates. When assessing willingness to work with a candidate from written transcripts, both female and male evaluators penalized female applicants for negotiating.
Missing context: Female evaluators ALSO penalized women for negotiating in written-transcript conditions. The backlash is not exclusively from male evaluators.

First offers as anchors: the role of perspective-taking and negotiator focus (Galinsky & Mussweiler, 2001)

Though uncited in the document, this general claim is well-established by Galinsky & Mussweiler 2001 and subsequent research. The anchoring effect of first offers is one of the most replicated findings in negotiation research.

Source quote:
whichever party, the buyer or seller, made the 1st offer obtained a better outcome. 1st offers were a strong predictor of final settlement prices.

The r=.85 figure is confirmed from Galinsky & Mussweiler 2001 Study 3 (chemical plant negotiation). The document cites the Columbia review paper rather than the original 2001 JPSP paper, making it a secondary citation. The statistic itself is accurate.

Source quote:

Hypothesis-Consistent Testing and Semantic Priming in the Anchoring Paradigm: A Selective Accessibility Model (Mussweiler & Strack, 1999)
Details

The selective accessibility model was developed by Mussweiler & Strack (1999, 2000). Galinsky & Mussweiler 2001 applied this model to explain anchoring in negotiation. The mechanism description in the document accurately reflects the model.

First offers as anchors (Galinsky & Mussweiler, 2001)
Details

The paper confirms that focusing on one's own targets or the counterpart's alternatives neutralizes the anchoring effect. The document's characterization of 'focusing on their own goals' is a reasonable paraphrase of 'considering one's own target.'

Source quote:
focusing on information that was inconsistent with the implications of the first offer negated the effect of first offers on outcomes... considering the opponent's alternatives, their reservation price, or one's own target all negated the effect.

The Harvard PON article confirms the phantom anchor finding by Bhatia & Gunia. The effect is accurately described in the document.

Source quote:
negotiators who framed their offer relative to a phantom anchor (for example, $10,000 rather than $11,000 for a car) achieved better outcomes than negotiators who made the same offer ($10,000) without referencing a phantom anchor.

Getting to Yes (1981) is confirmed to be enormously influential: 15M+ copies, 35+ languages, widely taught in law, business, and diplomacy programs.

Details

The core finding about resistance to yielding is confirmed by the abstract. The document omits the '(or unknown)' qualifier — the meta-analysis found the effect held when resistance was high OR unknown, not only when high. The document's inference that 'being cooperative without being assertive led to conceding too much' is a reasonable interpretation but goes slightly beyond the abstract's language.

Decreasing concessions signal that you are approaching your limit. Recipients of decreasing concessions perceive inflated reservation prices and make less ambitious counteroffers — benefiting the party using this pattern.

The Impact of Concession Patterns on Negotiations (Tey, Schaerer, Madan & Swaab, 2021, OBHDP)
Details

The finding is confirmed by Tey et al. (2021): decreasing concessions create inflated reservation price perceptions in recipients, who then make less ambitious counteroffers. The 'disadvantage for offer recipients' means the pattern-user benefits. The document's characterization is accurate.

Source quote:
decreasing concessions causes recipients to make less ambitious counteroffers and reach worse deals... recipients perceive inflated reservation prices... results in a negotiation disadvantage for offer recipients

Details

The paper exists in JPSP 2004 with three experiments as stated. The abstract's 'strategic-choice perspective' supports the 'strategic signals' characterization. However, the paper's focus is on the INTERPERSONAL effects via an inference/tracking mechanism, not on deliberate strategic signaling per se. The document's framing is reasonable but slightly shifts emphasis.

Details

The abstract confirms that happiness led to fewer concessions relative to anger. The document's inference that counterparts 'infer the happy party is satisfied' is a reasonable interpretation of the tracking mechanism described in the paper, though the abstract focuses the mechanism description on anger rather than happiness.

negotiators who perceived their counterpart's anger as inauthentic conceded less than did negotiators who perceived it as authentic... the reverse pattern was found among negotiators who perceived their counterparts' emotions as inauthentic.

Babcock & Laschever's Women Don't Ask (2003) found that women were significantly less likely to initiate salary negotiations.
finding Section 6, Original Finding paragraph Cited: UC Davis ADVANCE
Women Don't Ask: Negotiation and the Gender Divide (Babcock & Laschever, 2003, Princeton UP)
Details

The book exists (Princeton University Press, 2003) and the core finding — women less likely to initiate salary negotiation — is well-documented. Men initiated negotiation 4x more often. The document's characterization is accurate.

Source quote:
Men ask for what they want twice as often as women do and initiate negotiation four times more... men are four times more likely to ask for higher pay.
Contradicting evidence: Kray, Kennedy & Lee (2023) found this gap has since reversed, which the document appropriately covers in the next section.

A 2023 Academy of Management Discoveries study found that women today negotiate pay as often — or more often — than men. The 'women don't ask' narrative no longer holds.

The paper exists in AMD 2023 as cited. The finding that women now negotiate as often or more often than men is confirmed (54% vs 44% in MBA sample). The document's claim is well-supported.

Source quote:
significantly more women than men reported negotiating their job offers — 54% versus 44%... the gender difference appeared to disappear around 1994 and reversed beginning around 2007

Relational framing reduces backlash: women who framed their negotiation in terms of organizational benefit were penalized less.
finding Section 6, Updated Evidence item 3 Cited: Harvard Kennedy School
How Can Women Escape the Compensation Negotiation Dilemma? (Harvard Kennedy School Gender Action Portal)
Details

The finding is confirmed: relational accounts (organizational framing) reduced backlash and improved outcomes for women negotiators. The document's characterization is accurate.

Source quote:
Two relational account strategies worked effectively for women: (1) Citing supervisor advice to negotiate, (2) Framing negotiation skills as organizational assets. These approaches improved both social and negotiation outcomes for women.

A 2023 Annual Review of Economics review concluded the gap stems more from institutional structures (promotion paths, information asymmetry) than from individual negotiation behavior.

Gender Differences in Negotiation: Can Interventions Reduce the Gap? (Recalde & Vesterlund, 2023, Annual Review of Economics)
Details

The paper exists in Annual Review of Economics (2023) as cited. Its argument that institutional changes are more effective than individual behavior change ('fix institutions, not women') aligns with the document's characterization. The document's claim is a reasonable summary.

Source quote:
initial efforts to push women to negotiate more like men have shifted to alter instead the conditions of the negotiation, resulting not only from wanting to consider policies that 'fix the institutions' rather than 'fixing the women'
Contradicting evidence: The review also notes unintended consequences of institutional interventions, which the document omits.
Missing context: The review cautions about unintended consequences of interventions like salary history bans.

Anger: Counterparts concede more — they infer the angry party has a high limit and is close to walking away.
finding Section 5, Emotion table row 1 Cited: Van Kleef et al., 2004 (PubMed 14717628)
Van Kleef, De Dreu & Manstead, 2004, JPSP
Details

The abstract confirms both the effect (more concessions to angry opponents) and the mechanism (inferring the opponent's limit). The document's description matches the source.

Source quote:
participants conceded more to an angry opponent than to a happy one. Experiment 2 showed that this effect was caused by tracking — participants used the emotion information to infer the other's limit, and they adjusted their demands accordingly.
Contradicting evidence: Effect depends on moderating conditions (power, time pressure, authenticity) tested in separate papers.
