Fluency, the Feeling of Rightness, and Analytic Thinking Valerie Thompson Gordon Pennycook Jonathan Evans Jamie Prowse Turner
Metacognitive Reasoning Theory Dual Process Theories Automatic Type 1 processes produce a default answer that may or may not be further analysed by deliberate Type 2 processes What processes monitor Type 1 outputs? When is the default accepted or rejected? Feeling of Rightness (FOR) Accompanies Type 1 output Feeling of certainty about that output Akin to other metacognitive experiences, such as Feeling of Knowing, Judgement of Learning, etc.
FOR and Type 2 engagement FOR should predict P(Type 2) processing: Weak FOR → high P(Type 2) Strong FOR → low P(Type 2) → compelling illusions (Wason, Linda) FOR, like other metacognitive experiences should depend on fluency of retrieval Fluency: Ease with which answers come to mind More fluent → Strong FOR Less fluent → Lower FOR
Evidence for Metacognitive Reasoning Theory (Thompson, Pennycook, & Prowse Turner, under review) Conditional inference task if p, then q; p. q? N = 64, familiar materials, varied belief by validity, logic instructions, yes/no response Conditional syllogisms If p, then q; if q, then r; p. r? N = 48, non-sense middle terms, varied belief by validity, logic instructions, yes/ no response Base rate task De Neys & Glumicic (2008): personality descriptions + baserate N = 128, congruent, incongruent, neutral problems, no normative instructions, estimated probability

Evidence Summary FOR predicts Type 2 engagement: Rethinking time FOR ↑ → ↓ Rethinking time Probability of changing initial answer FOR ↑ → ↓ Answer change (probability and degree) FOR predicted by fluency to generate initial answer time to generate Answer 1 ↓ →↑ FOR Therefore, if fluency → FOR and FOR → Type 2 processing, then: Ho: Manipulating fluency should affect Type 2 processing 1. Fluency of processing 2. Fluency of production
Processing Fluency and Type 2 Engagement Alter et al. (2007) manipulated fluency of processing Experiment 1: CRT (Fredericks, 2005) clear (M = 1.9) vs degraded text (M = 2.5) Experiment 3: Representativeness and base rates (Tom W) puffed cheeks (r =.43) vs furrowed brow (r =.74) separate group answered trivia; puffed more confident Experiment 4: Syllogisms clear (M = 43%) vs degraded text (M = 64%) Separate group estimated difficulty without solving; clear less difficult Concluded fluency → Type 2 processing

Fluency of Responding vs Fluency of Processing Ho: FOR is determined by the fluency with which initial answer produced Manipulating fluency of processing should affect FOR only if it affects fluency of production E1 and E2: text manipulation had no effect on fluency of production Experiment 3: Manipulate fluency of production
Experiment 3 with Jonathan Evans Matching bias in Wason task Full matching paradigm, arbitrary content e.g., if the letter is not V, then the number is 8 Implicit negations Cards presented one at a time Do you need to turn this card over? 32 trials (4 rules x 4 cards x 2 repetitions) Two-response paradigm 24 U. of Saskatchewan students
Relative to non- matching, matching cards should be: “selected” more often responded to faster (fluency) promote stronger FOR’s engender less T2 processes: rethinking time probability of change number correct? Experiment 3 with Jonathan Evans DVMatchNon- Match t “Select”-1 (%) ** “Select”-2 (%) * RT-1 (sec) ** FOR (/7) ** Rethink (sec) * Change (%) ** Correct (%) 61 < 1
Experiment 3 with Jonathan Evans ** * * t (21) > 4.20, p <.001
Conclusions and Future Directions FOR predicts Type 2 engagement Rethinking time, probability of changing answers Fluency of responding affects FOR Manipulations that decrease speed of responding: decrease FOR’s increase Type 2 engagement Fluency of processing per se does not affect FOR’s Hard vs easy to read text did not affect FOR’s or Type 2 judgments But may affect Type 2 processing (Alter et al, 2007) Differences in participant population, method, number of problems Next: Fluent and disfluent versions of the CRT Syllogisms: accessibility of conclusion Matching in the truth table task
