Meaning
Describing an idea, plan, or scheme that is poorly thought out, immature, or improperly developed before being announced or attempted; also extended to people as foolish or naive. Informal and dismissive, and today more often applied to plans than to persons. Informal and always disparaging; it faults preparation and judgment rather than intent. Regional use: General English.
Origin
A bread metaphor: loaf or dough removed from the oven before it is fully cooked is literally half-baked, heavy, and unusable, and the literal adjective is old - Merriam-Webster gives a first known use of 1562 for the underdone sense while Etymonline dates the compound to the 1620s, a small discrepancy between references. The figurative application to anything incomplete or immature is much younger: Etymonline dates the colloquial figurative sense of 'silly, immature' to 1855. The step from doughy loaf to underdone thinking is an obvious and uncontested inference from the literal sense; there is no competing origin story.
