Abstract: Recent studies on logical reasoning have suggested
that people are intuitively aware of the logical validity of syllogisms
or that they intuitively detect conflict between heuristic responses and
logical norms via slight changes in their
feelings. According to logical intuition studies, logically valid or
heuristic logic no-conflict reasoning is fluently processed and induces
positive feelings without conscious awareness. One criticism states that
such effects of logicality disappear when
confounding factors such as the content of syllogisms are controlled.
The present study used abstract propositions and tested whether people
intuitively detect logical value. Experiment 1 presented four logical
propositions (conjunctive, biconditional, conditional,
and material implications) regarding a target case and asked the
participants to rate the extent to which they liked the statement.
Experiment 2 tested the effects of matching bias, as well as intuitive
logic, on the reasoners' feelings by manipulating whether
the antecedent or consequent (or both) of the conditional was affirmed
or negated. The results showed that both logicality and matching bias
affected the reasoners' feelings, and people preferred logically true
targets over logically false ones for all forms
of propositions. These results suggest that people intuitively detect
what is true from what is false during abstract reasoning. Additionally,
a Bayesian mixed model meta-analysis of conditionals indicated that
people's intuitive interpretation of the conditional
"if p then q" fits better with the conditional probability, q given p.
