My research projects

Feldman, G. What is normal? Contrasting the impact of past behavior, expectations and social norms normality categories over regret in the action-effect. DOI: 10.13140/RG.2.2.17274.39364

The widely-replicated action-effect (Kahneman & Tversky, 1982a) describes a phenomenon in which negative outcomes are associated with higher regret when they are a result of action compared to inaction. The highly influential norm-theory (Kahneman & Miller, 1986) theorized that the effect can be explained using the concept of normality, arguing that inaction is more ‘normal’. We aimed to clarify the concept of normality and examine the impact on regret in the action-effect by contrasting three identified categories: past-behavior normality, role/situational expectations normality, and social-norms normality. In three exploratory experiments (N1 = 213, N2 = 300, N3 = 303) and one concluding pre-registered combined experiment (N = 403) we found that the three normality categories had distinct effects with consistent medium to strong impact on the regret action-effect (d = .51 to d =.85) and no interactions. The action-effect was significantly weakened into an inaction-effect in the joint effects of any two types of the three normality categories (d = 1.56 to 1.61) and with all three combined (d = 2.75). In addition, we conclude three replications for each of the normality categories effects, overall nine successful replications of previous findings.

 

Feldman, G. Regret-action effect: Action-inaction asymmetries in inferences drawn from perceived regret. DOI: 10.13140/RG.2.2.35152.76809/1

Emotions are used to infer information about people and to make sense of ambiguous situations. Extending the literature on cognitive effects of action-inaction asymmetries regarding regret, we pre-registered hypotheses for asymmetries in interpretations of others’ experiences of regret. In four experiments, we examined the impact of perceived regret or no-regret on action-inaction attributions in ambiguous situations and found consistent evidence for a “regret-action effect”. Participants interpreted regret as more likely a result of taking action than of not acting, compared to no-regret, even before outcome was known to the decision maker and regardless of actual outcome. Emotions were also used to infer the social context as the regret manipulation affected perceived action-inaction norms, with no-regret associated with weaker action norms (compared to the regret and control conditions).

 

Feldman, G. Personal values and moral foundations: Examining relations and joint prediction of moral variables. DOI: 10.13140/RG.2.2.32570.49600/2

We examined the relationship between personal values and moral foundations by conducting a mini meta-analysis of the values-foundations links of five large-scale cross-cultural samples (N = 32,492). We further tested whether the two theories predicted unique variance in moral variables. We found support for values and foundations as having consistent and theoretically meaningful relationships. Broadly, self-transcendence versus self-enhancement values dimensions were associated with individualizing foundations, whereas conservation versus openness-to-change values dimensions were associated with binding foundations. Links between low-level values and foundations followed the expected theoretical values theory circumplex structure sinusoidal pattern. Dimensions of the two theories predicted unique variance in morality attitudes, behavior, and individual-differences.

 

Feldman, G., Kutscher, L., & Yay, T. Omission and commission in judgment and decision making: A review of biases and cognitive asymmetries related to action and inaction. DOI: 10.13140/RG.2.2.15958.09289

Research on action and inaction in judgment and decision making now spans over 35 years, with ever growing interest. Accumulating evidence suggests that action and inaction are perceived and evaluated differently, affecting a wide array of psychological factors from emotions to morality. These asymmetries have been shown to have real impact on choice behavior in both personal and interpersonal contexts, with implications for individuals and society. We review nine impactful action-inaction related phenomena, with a summary and comparison of key findings and insights. We map links between the effects and discuss conceptual challenges and empirical similarities and differences. Together, these aim to contribute towards an integrated understanding of the human psyche regarding action and inaction.

Feldman, G., Kutscher, L., & Yay, T. What is action, what is inaction? A review of action-inaction biases and recommendations for term use and typology. DOI: 10.13140/RG.2.2.27961.83046

Research on action and inaction now spans over 35 years, with ever growing interest. Still, the terms action and inaction have not been thoroughly discussed and are often poorly defined and commonly misunderstood. This often resulted in confounded use and much confusion, and may contribute to unclear and/or inconsistent findings in empirical work that limit generalizability and integration. In this review, we aim to offer an organizing framework for scholarly research on action-inaction. We first cover several widely-studied action-inaction biases and demonstrate some of the challenges and issues in the way action and inaction have been conceptualized and tested. We then build on those to identify a typology of nine different uses of the terms. Finally, we provide six recommended guidelines for defining and theorizing about action and action in future scholarly research.

 

 

Supervised research (replications & meta-analyses)

*Yay, T, & ^*Feldman, G. Action-inaction asymmetries in moral scenarios: Replication of the omission bias examining morality and blame with extensions linking to causality, intent, and regret. DOI: 10.13140/RG.2.2.10240.74242

Omission bias is the preference for harm through omissions over harm through commissions. In a pre-registered experiment (N = 313), we successfully replicated an experiment from Spranca, Minsk, and Baron (1991), considered a classic demonstration of the omission bias, in an adjusted between-subject design addressing concerns regarding the generalizability of the effect beyond within-subject experiments. Participants in the harm through commission condition(s) rated harm as more immoral and attributed higher responsibility compared to participants in the harm-through-omission condition (d = 0.40 to 0.52). We examined several extensions. An action-inaction asymmetry was also found for causality and intent, in that commissions were attributed stronger action-outcome links and higher intentionality (d = 0.21 to 0.58). The effect for regret was opposite from the classic findings on the action-effect, with higher regret for inaction over action (d = -0.26 to -0.19). Overall, higher perceived causality and intent were associated with higher attributed responsibility, and with lower perceived morality and regret.

 

*Gao, Y., *Yao, D., & ^Feldman, G. Owning leads to valuing: Meta-analysis of the Mere Ownership Effect. DOI: 10.13140/RG.2.2.13568.33287/1

Mere ownership effect is the phenomenon that people tend to value what they own more than what they do not own. This classic effect is considered robust, yet evidence is inconsistent, effect size varies across studies, and the effect is often confused for or confounded with other classic phenomena, such as endowment or mere exposure effects. We conducted a pre-registered meta-analysis of 26 samples (N = 3132) resulting in medium effect-size for psychological ownership on valuing (g = 0.59, 95% confidence intervals [CI] [0.47, 0.70]). Moderator analyses showed that object materiality, use of replica, and valuing type were the strongest moderators, compared to weaker effects for loss aversion, type of ownership (implicit/explicit), level of exposure, and study design (between/within). Mere ownership effects were different than null across all moderator categories and publication bias corrections. We conclude that psychological owning indeed leads to valuing, regardless of endowment, loss-aversion, and mere-exposure effects.

 

*Yao, D., *Gao, Y., & ^Feldman, G. Impact of ownership on liking and value: Replication of three ownership effect experiments. DOI:
10.13140/RG.2.2.16962.8416

Ownership increases liking and the perceived value of owned objects (Beggan, 1992). In a pre-registered study, we conducted a close replication of three ownership effect experiments using different paradigms (N = 311). We successfully replicated Nuttin’s (1987) name-letter effect in Part 1, and Mandel’s (2002) endowment effect in Part 3. In these experiments, participants rated higher liking for letters of the alphabet when letters appeared in their first name (vs. when letters did not) (Part 1; d = 0.19) and set a higher price for an object when they were the owners (vs. non-owners) (Part 3; d = 0.65). However, we failed to find support for Irmak, Wakslak, and Trope’s (2013) endowment effect findings in Part 2 (target’s effect: d = 0.99) of price differences between sellers and buyers (replication effect: d = 0.10).

 

*Kutscher, L., & ^*Feldman, G. Impact of past behavior normality on regret: Meta-analysis of exceptionality effect. DOI: 10.13140/RG.2.2.12760.96005

Exceptionality effect is the phenomenon that people associate stronger regret with a negative outcome when it is a result of an exception (abnormal behavior) compared to when it is a result of routine (normal behavior). In this pre-registered meta-analysis, we examined exceptionality effect in 45 studies (N = 3933). An analysis of 34 experimental studies (n = 2716) showed medium to strong effect (g = 0.72, 95% confidence intervals (CI) [0.46, 0.97]) for past behavior on regret across several regret related measures (regret: g = 0.83, counterfactuals: g = 0.40, self-blame: g = 0.44, victim compensation: g = 0.44, offender punishment: g = 0.50). An analysis of 13 studies presenting a comparison of exceptional and routine behaviors simultaneously (n = 1217) revealed an even stronger exceptionality effect (converted g = 2.07, CI [1.59, 2.43]). We tested several theoretical moderators – norm strength, event controllability, outcome exceptionality, action versus inaction, and status quo. Exceptionality effect was stronger when the routine was aligned with the status quo option, when the exception represented an omission compared to a commission, and when the outcome was more common (less exceptional).

*Chandrashekar, S.P., *Yeung, S., Yau, K., ^Feldman, G., et al. Agency and self-other asymmetries in perceived bias and shortcomings: Replications of the Bias Blind Spot and extensions linking to free will beliefs. DOI: 10.13140/RG.2.2.19878.16961

Bias Blind Spot is the phenomenon that people tend to perceive themselves to be less susceptible to biases than others. In three pre-registered experiments with samples from Hong Kong and the United States (overall N = 969), we replicated two experiments (Study 1-Survey 2 and Study 2) from Pronin, Lin, and Ross (2002), the first published demonstration of the effect. Participants rated themselves lower than others in both susceptibility to biases (mini meta-analysis: dz = – 1.00) and personal shortcoming (mini meta-analysis: dz = – 0.34). The self-other asymmetry of susceptibility for biases was larger than that of personal shortcomings (dz = – 0.43). Thus, the replication findings provide strong empirical support for the bias blind spot phenomenon. Extending the replications, belief in free will was positively associated with the susceptibility to better than average effect, and also with a stronger self-other asymmetry in rating personal shortcomings.

 

*Ziano, I., *Wang, Y. J., *Sany, S., ^*Feldman, G., et al. Perceived morality of direct versus indirect harm: Replications of the preference for indirect harm effect. DOI: 10.13140/RG.2.2.29720.85760

Royzman and Baron (2002) demonstrated that people prefer indirect harm to direct harm: they judge actions that produce harm as a by-product to be more moral than actions that produce harm directly. In two preregistered studies, we successfully replicated Study 2 of Royzman and Baron (2002) with a Hong Kong student sample (N = 45) and an online American Mechanical Turk sample (N = 314). We found consistent evidential support for the preference for indirect harm phenomenon (d = 0.34, 95% confidence intervals (CI) [0.23, 0.45]), weaker than effects reported in the original findings of the target article (d = 0.70, CI [0.40, 1.00]). We also successfully replicated findings regarding reasons underlying a preference for indirect harm (directness, intent, omission, probability of harm, and appearance of harm).

 

*Chen, J., *Hui, L.S., *Yu, T., ^*Feldman, G., et al. Foregone opportunities and choosing not to act: Replications of Inaction Inertia effect. DOI:
10.13140/RG.2.2.29936.71685

Inaction inertia is the phenomenon that forgoing an initial, attractive opportunity decreases the likelihood of taking a subsequent opportunity that is less attractive, even when the subsequent opportunity offers positive value. We conducted two pre-registered replications of Tykocinski, Pittman, and Tuttle (1995) Experiments 1 and 2’s four scenarios in two samples (Hong-Kong students: n = 43; American online workers: n = 309). We found consistent findings across the two samples, with inaction inertia effect dependent on scenario used. Strongest effects were for the car scenario (d = -0.95 to -1.15), followed by ski scenario (d = -0.40 to -0.66), with mixed findings for fitness scenario (large-small contrast: d = -0.59; control contrast effects opposite to predictions) and weak to no effects for flyer scenario (d = -0.12 to 0.35). We conclude by recommending the car and ski scenarios for follow-up research on inaction-inertia, and discuss implications for future research.
