The occurrence of one expectation that has repeatedly formed a belief that it will still happen more than the others. System 1 makes an inference that since an event has been speculated to be happening concurrently, it likely to occur is high. An individual ends up making a biased conclusion. System 1 needs to be adequately tamed to reduce the direct inference from past concurrencies, due to the frequency of their occurrence. The stereotyping is one of the significant biases the brain performs. The brain has a way of creating or finding commonness in character traits and attaching them to another despite the lack of the relationship.
