- “Justify Your Alpha: A Response to Redefine Statistical Significance”, with Daniel Lakens and 86 further authors (this paper is intended as a commentary on research practice, of which I am a co-signer), (2018), Nature Human Behavior. Preprint. Press coverage: nature.com.
We propose to justify alpha levels based on cost/benefit analyses and prior likelihood of hypotheses, rather than keeping it fixed at conventional levels.
Consumers that buy products also bought by a majority of consumers are considered smarter than minority consumers. This is driven by the higher expected quality of majority products, and does not happen for taste-based products.
3. *” Impact of ownership on liking and value: Replications and extensions of three ownership effect experiments ” (2020), with Donna Yao, Yajing Gao, and Gilad Feldman. Journal of Experimental Social Psychology. Preprint.
Ownership increases liking and the perceived value of owned objects (Beggan, 1992). In a pre-registered study, we conducted close replications of three ownership effect experiments using different paradigms (two MTurk data collections; total n = 1312). We successfully replicated Nuttin’s (1987) name-letter effect with participants rating higher liking for letters of the alphabet for letters in their first names (vs. when letters did not) (d = 1.08 – 1.42). We found partial support for Mandel (2002), with higher price for an object when they were the owners (vs. non-owners) (d = 0.49 and 0.65) yet with mixed findings regarding the moderator. Finally, we failed to find support for Irmak, Wakslak, and Trope’s (2013) differences in price evaluations comparing sellers/owners and buyers (target’s effect: d = 0.99; replications: d = 0.01 and 0.10). Our results suggest that ownership effects may depend on the paradigm of choice. We discuss potential moderators of the ownership effect and suggest future research directions.
Successful replication of Study 2 of Rozyman and Baron 2002.
5. *”Slow Lies: Slower Responses Are Perceived As Less Sincere, Because Of Inferences Of Thought Suppression”., with Deming Wang (2021) Journal of Personality and Social Psychology. Preprint.
Slower responses are perceived as less sincere, because people think they are caused by thought suppression inferences and because they believe slower respondents are fabricating a novel answer. This effect is moderated for high-cost sentences, unacceptable opinions, by instructions to ignore speed, and if there is a believable reason for delay. Response speed bias potential guiltiness judgments, with worrying legal consequences.
6. * “Replication and extension of Alicke (1985) Better-than-Average Effects for Desirable and Controllable traits”, with Gilad Feldman and Cora Mok (2020). Social Psychological and Personality Science (IF: 3.53). Preprint.
Successful replication of the phenomenon for which people tend to think they are better than others on desirable and controllable features.
7. *”Replication of Tversky and Shafir, 1992, The Disjunction Effect” with Gilad Feldman and others (2021). Journal of Economic Psychology. Preprint.
Partially successful replication of Problems 1 and 2 of Tversky and Shafir, 1992.
8. * “Revisiting “Money Illusion”: Replication and Extension of Shafir et al. (1997)”, with Gilad Feldman and others (2021). Journal of Economic Psychology (ABS 2). Preprint.
Successful replication of “money illusion”, the phenomenon for which people take into account the nominal value of money rather than just looking at the real value (ie, perfectly adjust for inflation).

Unsuccessful replication of the effect of product size on impressions of status.

* “Late-Action Effect: Heightened Counterfactual Potency and Perceived Outcome Reversibility Make Actions Closer to a Definitive Outcome Seem More Impactful”, with Mario Pandelaere. Under 2nd round of review at Journal of Experimental Psychology: General. Preprint. Data and preregistrations.
People believe that actions closer to the end of an event have a higher impact than actions earlier on, because the actions closer to the end evoke a higher likelihood of counterfactual thinking and make an outcome seem less reversible.
* “You’d Use It More than Me: Overestimating Products’ Usefulness to Others Because Of Self-Serving Materialism Attributions”. Revise and resubmit at Journal of Consumer Psychology with Daniel Villanova. Preprint. Data and preregistration.
Consumers believe that similar others have find the same products more useful, because consumers think that others are more materialistic than they are.
* “Perceived Income Inequality: Why Pay Ratios Are Less Effective Than Median Incomes”, with Mario Pandelaere and Christophe Lembregts. Under review at Social Psychological and Personality Science. Preprint. Data and preregistrations.
Median employee pay is the major driver of fairness judgments and demand for political action, because it is easier to evaluate. People are much less sensitive to CEO absolute pay or CEO-to-employee pay ratio when making fairness judgments based on within-company income inequality data.
“Consumers Overestimate Product Effectiveness For Others”, with Anneleen van Kerckhove, Evan Polman, and Kaiyang Wu. Revise and resubmit at Journal of Consumer Research . Preprint.
Consumers believe the same products are more effective for others, because they believe to be more unique than other. This causes consumers to choose a higher quantity of product when they choose for the self, compared to others.
“Salary-Quality Beliefs”, with Birga M. Schumpe. Under review at Journal of Marketing. Preprint.
Consumers expect and perceive products made by well-paid employees to be of higher quality. This is driven by the belief that well-paid employees are more satisfied and exert more effort in production, which, in turn, results in higher quality products, which we call a “happiness lay theory of value”.
