Loss Aversion
A cognitive bias that describes why the pain of losing is psychologically twice as powerful as the pleasure of gaining.
Why it matters
People are hardwired to avoid losses.
This is partly because the feeling of losing is 2x more powerful than that of winning.
In UX, this can manifest in many ways.
For example, after entering personal information into a form, the user may be nervous about clicking the 'back' button in their browser.
Their aversion to loss in this example, is losing the data they've entered , and therefore their progress.
