Teaching Informal Logical Fallacy Identification with a Cognitive Tutor

In this age of fake news and alternative facts, the need for a citizenry capable of critical thinking has never been greater. While teaching critical thinking skills in the classroom remains an enduring challenge, research on an ill-defined domain like critical thinking in the educational technology space is even more scarce. We propose a difficulty factors assessment (DFA) to explore two facto...

On the interpretation of diagnostic tests: a common logical fallacy.

5%). Recoveries were similar when samples were sonicated before or after addition of perchloric acid. The compounds were determined in seven 250ML portions of a pooled whole-blood sample; the within-day CVs were 4.3% for 5-HT and 2.1% for TRP. Determinations made on 20-ML samples of pooled wholeblood (prepared by adding 10 ML of ascorbic and perchloric acid) gave CVs of 9.7% for 5-HT and 6.8% f...

Conflict Sensitivity and the Conjunction Fallacy: Eye-tracking Evidence for Logical Intuitions in Conjunction Probability Judgments

Recent evidence shows that, contrary to what is commonly assumed, people who are pressured to think fast are also less likely to provide a heuristic judgment when heuristic and logical considerations point to conflicting answers in a conjunction fallacy task (Vallée-Tourangeau & FaureBloom, under review). The present study explores this finding using an eye-tracking methodology. Eye movements f...

Debunking mathematically the logical fallacy that cancer risk is just “ bad luck ”

Tomasetti and Vogelstein recently proposed that the majority of variation in cancer risk among tissues is due to “bad luck,” that is, randommutations arising during DNA replication in normal noncancerous stem cells. They generalize this finding to cancer overall, claiming that “the stochastic effects of DNA replication appear to be the major contributor to cancer in humans.” We show that this c...
