Doing the same thing twice and expecting different feelings, not results.
means The quality of thinking or acting in ways that don't follow logic or sound reasoning, often driven by emotion, bias, or habit instead.
from From Latin irrationalis — 'in-' (not) plus 'rationalis' (reasonable, endowed with reason), itself from 'ratio' meaning reckoning, calculation, or reason. 'Ratio' traces back to the verb 'reri,' to think or calculate. So the word's bones literally mean 'without the capacity to reckon things out' — the opposite of a mind doing its sums.
