Ten sources not to rely on
The Kalamas are told not to accept a teaching on the strength of repeated oral report, lineage tradition, rumor, scripture, logical deduction, inference, reasoned appearance, agreement with a view already held, the speaker's apparent competence, or reverence for the teacher. Each item names a common reason people give for belief, and none of them settles whether the belief is sound. The list moves where the burden of proof sits: away from where a claim came from and onto what it does.
