Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q1 i? Inspection of the adults' answers to why magnets are bent into U form showed impulsive, uncritical, and confused thinking to a notable degree. → Thorndike 1922 q1 i? The authors claim the difference between adult and child thinking is in part a consequence of specialized habits rather than all-pervasive and constitutional. → Thorndike 1922 (2)

q1 · i? · qualitative · r2

The authors' qualitative inspection of twenty answers to the U-magnet question, given after ten hours of study, found "impulsive, uncritical, and confused thinking to a notable degree." This is the writers' interpretation of the written work, not a tested comparison.

"Many of them show an impulsive, uncritical, and confused thinking to a notable degree—to the person who is really master of the topic."

q1 · i? · causal · r1

The authors' interpretive conclusion from inspecting the adults' work: the adult-child contrast in rationality is "in part, a consequence of specialized habits." No effect size or test is reported; this is the writers' opinion based on the collected work.

"our inspection of the work of this score of superior trained adult thinkers strongly suggests that the paradox has a large element of truth, that the difference in thinking is not all-pervasive and constitutional, but is, in part, a consequence of specialized habits."
