Why does primacy bias matter?

Primacy bias matters because it is an indication that our brains are disproportionately influenced by first impressions when processing information. Knowing this, we can use the primacy bias to our advantage.

For example, when studying, we can start our session with the most difficult topic. We can also revisit any topics or concepts we found hard at the end of our session. In this way, we can take advantage of recency bias as well.
