Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input.
These are direct phenotypic benefits, sensory bias, the Fisherian runaway hypothesis, indicator traits and genetic compatibility. In the majority of systems where mate choice exists, one sex tends to be competitive with their same-sex members [ 4 ] and the other sex is choosy (meaning they are selective when it comes to picking individuals to ...
One of the dilemmas included in the trolley problem: is it preferable to pull the lever to divert the runaway trolley onto the side track?

[2] Precopulatory and postcopulatory mate-guarding occurs in insects, lizards, birds and primates.
