It's not counterproductive at all. Knowing how to deal with such biases (whether they're internal or external) makes them easier to overcome.

For example, I'm self-taught, and while I have many years experience now and have done some significant projects, I still second guess myself quite a bit. (This is often called "Imposter Syndrome", see e.g. http://en.wikipedia.org/wiki/Imposter_syndrome.) I found it tremendously helpful to discover that people I've looked up to for years have felt the same way, and had helpful suggestions for getting over the internalized anxiety.

Everybody has nagging fears like this. Learning how to see them for what they are and to avoid making things worse for other people benefits everybody.
