Furthermore, allowing cognitive biases enables faster decisions which can be desirable when timeliness is more valuable than accuracy, as illustrated in heuristics. They may lead to more effective actions in a given context. While cognitive biases may initially appear to be negative, some are adaptive. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, and irrationality. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Individuals create their own 'subjective reality' from their perception of the input.
A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment.
