the frequency format hypothesis suggests that people are better able to work with information presented as frequencies than presented as probabilities. why might this be the case? multiple choice question human brains evolved to notice how often things occur, not how likely they are to occur. probability calculation is a more difficult cognitive task because it necessarily involves the manipulation of symbols. human brains evolved to process frequencies in the left hemisphere and probabilities in the right hemisphere. human brains evolved to process frequencies explicitly and probabilities implicitly.
