Negative selection bias

Negative selection bias refers to a tendency where certain options or incidents are excluded based on a negative outcome or characteristic, often leading to skewed results or perceptions. This bias is prevalent in various aspects of human decision-making and perception, including media, psychology, and economic behavior.

For example, in the realm of venture capital, as explained by Henry Ward, the phenomenon of negative selection bias was prevalent when venture capitalists would avoid companies that used investment bankers to raise funds. This was partly because the traditional venture capital model was confined to a few firms and using an intermediary like an investment banker was viewed negatively. This bias can distort the venture ecosystem by limiting opportunities for companies that might only seek to expand their options through intermediaries 1.

Additionally, in psychological terms, negative selection bias is part of a larger negativity bias where negative experiences or emotions exert a greater influence on an individual's psychological state than neutral or positive ones. This is evident in various domains, including news consumption, social interactions, and memory, where negative information tends to have a disproportionately large effect 2.

These examples underscore the pervasive impact of negative selection bias across multiple fields, affecting everything from business decisions to interpersonal relations and individual psychological well-being.
