6 Cognitive Biases That Are Messing Up Your Decision Making

We have a tendency to stubbornly hold on to a number once we hear it and gauge all other numbers based on the initial number, even if the information is not that relevant.

For example, if customers are limited to 'four per customer' they are more likely to buy four, even if they did not initially intend to do so.

Our brains like shortcuts and ideas that are consistent. 

When someone makes a good first impression during an interview, their professional accomplishments are more likely to be viewed as similarly positive later.

The idea is once we are invested in something, we become less likely to abandon it, even if it is clear that it will ultimately fail.

We frequently lose more if we don't make the hard decision to cut our losses.

We are more likely to listen to success stories than failures. The result is that we often over-estimate the likelihood of success in risky ventures.
