The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
After experiencing a bad outcome with a decision problem, the tendency to avoid the choice previously made when faced with the same decision problem again, even though the choice was optimal. Also known as "once bitten, twice shy" or "hot stove effect". [106] Mere exposure effect or familiarity principle (in social psychology)
It is part of cognitive science, and is a distinct cognitive bias that occurs once a decision is made. For example, if a person chooses option A instead of option B, they are likely to ignore or downplay the faults of option A while amplifying or ascribing new negative faults to option B.
The approach based on optimality models in biology is sometimes called optimality theory. [1] Optimal behavior is defined as an action that maximizes the difference between the costs and benefits of that decision. Three primary variables are used in optimality models of behavior: decisions, currency, and constraints. [2]
For example, Judge Richard Posner once remarked that falsus in uno was a "discredited doctrine" based on "primitive psychology". This assertion was not made in relation to fraudulent documentation or a "material" inconsistency; rather, it was based on what the court characterizes as "innocent mistakes, trivial inconsistencies, and harmless ...
The effect grew even more pronounced when statements were repeated twice and yet more pronounced when they were repeated four times. The researchers thus concluded that memory retrieval is a powerful method for increasing the so-called validity of statements and that the illusion of truth is an effect that can be observed without directly ...

Double-loop learning is used when it is necessary to change the mental model on which a decision depends. Unlike single loops, this model includes a shift in understanding, from simple and static to broader and more dynamic, such as taking into account the changes in the surroundings and the need for expression changes in mental models.
