The Origins of Bias in the Brain
In order to think (and hopefully learn), the brain requires well-functioning Attention systems and well-functioning Memory systems. Attention and Memory systems require lots of energy, which we measure as cognitive load.
Bias
As the brain always seeks efficiency, it seeks to conserve energy where possible. One way it does this is through heuristics, or short-cuts, which develop through habituation. Heuristics can lead to bias. Bias, in turn, reinforces heuristics.
