Slide 1

    Expectations of Frequency Affect Attentions
    Andrew Bellenkes conducted research on this expectation and found that if people expect something to happen with a particular frequency. They often miss it if it happens more or less than their expectation. The video is about airport security personnel frequently miss dangerous weapons due to unlikely encounters everyday. Security personnel are looking for common things such as lotion bottles, liquids but not bomb parts or guns.
