Behaviors of humans are very flexible and they tend to base their perception on what they see after processing information about the world.

People are often influenced their social environment rather than what they sense or experience.
The findings showed that people are likely to be influenced by conditioning or the surrounding environment rather than what they sense or experience.
The behavior of individuals can often evolve to be determined by a set of inherited genetic tendencies that accurately predict social relationships, including their likely relatedness to other members of their community, and their surroundings rather than in direct response to what they sense or experience.
The study, published in the journal PLOS Computational Biology, aims to explore why some individuals evolve to be genetically programmed to be nice, while others stay nasty.
The theory of kin selection explains the evolution of helping when relatives interact. It can be used when individuals in a social group have different sexes, ages or phenotypic qualities, but the theory has not been worked out for situations where there is a genetic polymorphism in helping, the researchers said.
Thus, for the study, the team used colony-living microbes as inspiration to explore why some individuals are by nature generous and others less so.
"What we have been able to show is how you can get a situation where you end up with distinct levels of genetically determined niceness coexisting within populations," Dall noted.
