Area of Science:

• Psychology
• Behavioral Economics

Background:

• Previous research indicated that individuals perceive future unpleasant experiences as more aversive.
• A critique questioned the reliability of these findings due to potential publication bias in the original study.
• The critique suggested that unpublished negative results might have been excluded, thus inflating the observed effect.

Purpose of the Study:

• To address criticisms regarding publication bias and validate the reliability of prior findings.
• To investigate the robustness of the effect by including all available study data.

Main Methods:

• A meta-analysis was conducted on all studies, encompassing both published and unpublished research.
• This approach aimed to provide a comprehensive assessment of the effect size and significance.
• The meta-analysis directly utilized available data rather than relying on estimations of missing studies.

Main Results:

• The meta-analysis confirmed the reliability of the original findings.
• The inclusion of unpublished studies did not diminish the significance or strength of the observed effect.
• The effect of anticipating future unpleasantness on perceived aversion was consistently demonstrated.

Conclusions:

• The tendency to remember future unpleasant experiences as more aversive is a reliable psychological phenomenon.
• Directly accessing and analyzing all available data (including unpublished studies) is a more valid approach than estimating publication bias.
• The findings underscore the importance of transparency and data sharing in scientific research.
