Definition
先入为主 is a four-character idiom meaning that the first impression or belief one forms tends to dominate and resist change. It's often used to caution against judging things too quickly based on initial exposure, or to explain why early information carries disproportionate weight. The phrase literally translates to 'the first to enter becomes the master.'
