Psychological determinism is something I feel the need to resist.
You might have guessed that from posts like this one, in which I react to the seeping snake oil that is personality testing. One of the reasons that I react against all this kind of stuff is the fact that it would tell us that we can not change- that our die was cast in the DNA we grew from and therefore we should just conform to our stereotype.
I do not concur because I do not think the science can support such narrow determinism. Also I stand as a person in much need of change. I am not the best that I can be. I am not the finished article. At age 47 the broken bits of me still need mending and the sinful bits of me need forgiving more than ever. I no longer have the excuse of immaturity.
This short TED talk says some interesting and hopeful things about the continuing possibilities of change;
We are also better able to see the things we want to change in retrospect, because we’ve experienced the consequences. It can be much harder to see the things that need changing in the present.
I recently wrote a post that relates to this, I thought you might be interested.
