All Psychological Phenomena

Psychological phenomenon entities are the specific, named cognitive and social effects this atlas documents, biases, heuristics and observed patterns of thought and behavior such as confirmation bias, the bystander effect and the sunk cost fallacy, grouped into bands led by Decision-Making and Judgment Biases and Social Biases and Group Effects, drawn from the editorial split used by Wikipedia's own List of cognitive biases article and grown considerably past its founding entries by later mint waves. A phenomenon is a specific documented effect, narrower than a theory, which is the broader explanatory account that may explain several phenomena at once, and narrower than a study, which is the particular research project that first identified or tested one. This band is where a reader browses psychology by its catalogue of named mental shortcuts and their failure modes, the single largest and fastest growing band in the atlas, with comprehensive real world coverage of the field's documented bias and heuristic literature as the ongoing target rather than any fixed list.
