The thumb your brain keeps on the scale while swearing it isn't weighing anything.

means A tendency to lean toward or against something in a way that skews judgment, often without the person noticing it.

from Comes from Old French 'biais' meaning slant or oblique, originally a bowls (lawn-bowling) term for the weighted, lopsided ball that curved as it rolled instead of going straight. By the 1500s English speakers had borrowed the word for any slanted tendency in a person's thinking — the mental equivalent of a ball that just won't roll true.
