What would happen if you asked me for my email address and I told you it was email@example.com?
How might your perception of me be shaped by that one piece of information? What if I told you it was a gmail address? Would that draw any reaction at all?
If we’re honest, we all know that we routinely draw multiple, broad conclusions from a single piece of information. Like an email address, or a LinkedIn photo.
This is an example of implicit bias.
