BIAS OF THE WEEK

Default Effect

In three conferences, participants were divided into two groups:

1. Standard menu registration with the option to choose vegetarian

2. Vegetarian menu registration with the option to choose non-vegetarian.

In group 1 only 6% ate a vegetarian menu in contrast to 87% in group 2.

When faced with different options, we tend to stick with the one selected by default.
