“I knew it!”
We congratulate ourselves when information seems to confirm exactly what we were thinking and expecting.
Data and information is influenced by the lens through which we process that information. (All data, I promise you.)
It is possible for someone to have the opposite opinion or expectation, get the same new information you did, and also say, “I knew it!”
Welcome to confirmation bias.
This is not proactive data manipulation for your own ends. This is simply about interpretation.
Confirmation bias is neither good nor bad. It just is. The important thing is to recognize that you might be experiencing it – that anyone might be experiencing it. That small step will allow you to be open to other considerations, instead of being stuck in your own limitations.
