Minorities, Measured Cognitive Skills and the Earnings of Canadians (Working Paper 26)

This paper uses the Statistics Canada Survey of Literacy Skills in Daily Use (LSUDA) to investigate minority-“white”(i.e., non-minority) income differences and the role education and English/French literacy and numeracy skills play in those patterns. There are three principal sets of findings. First, among males, some visible minority groups have substantially lower levels of the measured language and number skills than whites and other more economically successful minorities, and in some cases these differences play a significant role in explaining the observed income patterns. The minority-white income gaps are, however, much smaller for women, and the literacy and numeracy variables do not have much of a role to play in explaining those differences. Second, for men, the minority-white income gaps are largely confined to immigrants, and there are no significant differences amongst the native-born once various factors which affect incomes (including education and the literacy and numeracy measures) are taken into account. For women, though, minority-white income differences only emerge for certain Canadian-born groups when they are differentiated from immigrants, for whom different gaps become apparent. Finally, the measured returns to literacy and numeracy differ significantly by ethnic group and sex. Various implications of the findings are discussed.

Effects of introspection on meta and structural attitude bases

Introspection is the process by which individuals question their attitudes; either questioning why they hold their attitudes (Why introspection), or how they feel about a particular attitude object (How introspection). Previous research has suggested that Why-introspection induces attitude change, and that Why and How introspection influence attitude-behaviour consistency,persuasion, and other effects. Generally, psychologists have assumed that affective and cognitive attitude bases are the mechanism by which introspection leads to these effects. Leading perspectives originating from these findings suggest that either Why introspection changes the content of cognitive attitude bases (the skewness hypothesis), or increases the salience of cognitive attitude bases (the dominance hypothesis); whereas How introspection may increase the salience of affective attitude bases (another part of the dominance hypothesis). However, direct evidence for these mechanisms is lacking, and the distinction between structural and meta bases has not been considered. Two studies investigated this gap in the existing literature. Both studies measured undergraduate students’ attitudes and attitude bases (both structural and meta, affective and cognitive) before and after engaging in an introspection manipulation (Why introspection / How introspection / control), and after reading a (affective / cognitive) persuasive passage about the attitude object. No evidence was found supporting either the skewness or dominance hypotheses. Furthermore, previous introspection effects were not replicated in the present data. Possible reasons for these null findings are proposed, and several unexpected effects are examined.
