People
remember you for the things you do. Sadly, they recall negatives more
than positives.
The
human brain is programmed to react to bad events more significantly
than good ones. To illustrate, in a 2012 study, subjects who lost a
certain amount of cash expressed more intense emotions than those who
gained the same amount. When applied to a business' reputation, many
people will tend to believe negative reviews, and perceive a business
accordingly, even when the reviews are unfounded.
