The false-consensus effect (FCE) was observed across all age groups, but was weakest in older students who showed the lowest egocentrism. Egocentrism varied by age, with older adolescents being most egocentric and old-age home residents showing the highest levels.

Area of Science:

  • Psychology
  • Social Psychology
  • Developmental Psychology

Background:

  • The false-consensus effect (FCE) is the tendency to overestimate the extent to which others share one's beliefs and behaviors.
  • Egocentrism, a cognitive bias, influences social perception and decision-making.
  • Understanding how age and egocentrism interact with the FCE is crucial for social cognition research.

Purpose of the Study:

  • To investigate the prevalence of the false-consensus effect (FCE) across different age groups in Israel.
  • To examine the relationship between egocentrism, measured by the Interpersonal Reactivity Index, and the FCE.
  • To explore age-related differences in both FCE and egocentrism.

Main Methods:

  • Participants from four age groups (older adolescents, adults, old-age home residents, older university students) completed a 12-item FCE questionnaire.

  • The Interpersonal Reactivity Index (IRI) was used to measure egocentrism.
  • Statistical analyses were performed to compare FCE strength and egocentrism scores across groups and examine correlations.

    • Main Results:

    • The false-consensus effect (FCE) was present in all four age groups studied.
    • Older students exhibited a significantly weaker FCE and the lowest levels of egocentrism.
    • Egocentrism levels were highest in old-age home residents, followed by adults, then older adolescents, with older students being the least egocentric.

    Conclusions:

    • Age influences both the false-consensus effect (FCE) and egocentrism, with older students demonstrating a reduced FCE potentially linked to lower egocentrism.
    • Egocentrism appears to be a significant factor in social perception across the lifespan.
    • No direct correlation was found between the magnitude of the FCE and egocentrism scores in this study.
