Single Idea 18690

[filed under theme 14. Science / C. Induction / 1. Induction ]

Full Idea

Most theories of induction claim that it should depend primarily on the similarity of the categories involved, but then the type of property should not matter, yet research shows that it does.

Gist of Idea

Induction is said to just compare properties of categories, but the type of property also matters

A Reaction

I take this to be good empirical support for Gilbert Harman's view that induction is really inference to the best explanation. The thought (which strikes me as obviously correct) is that we bring nested domains of knowledge to bear in induction.

Induction is reasoning from the observed to the unobserved [Ladyman/Ross]
Induction is inferences from examined to unexamined instances of a given kind [Okasha]
Psychologists use 'induction' as generalising a property from one category to another [Machery]
