For social class we found a mixed pattern of results: educational attainment
and occupation status both showed small negative associations
with overestimates of social class mobility, whereas subjective
social class rank showed a small significant positive association with
mobility overestimates. Income was not reliably associated with mobility
overestimates. Conservatives tended to show a moderate tendency
to overestimate social class mobility relative to more liberal participants.
Trait optimism did not exhibit a reliable positive association
with social class mobility estimates. All measures of social class showed
small to moderate associations with trait optimism and no significant
associations with political ideology.
