Full Idea

It is sometimes said that inductive reasoning is 'defeasible', meaning that considerations that support a given conclusion can be defeated by additional information.

Gist of Idea

Induction is 'defeasible', since additional information can invalidate it

A Reaction

True. The point is that being defeasible does not prevent such thinking from being rational. The rational part of it is to acknowledge that your conclusion is defeasible.
