There is a piece of research by Harvard University which is very relevant right now.
Their research looks at unconscious/hidden bias across a number of different areas, e.g. race, religion, gender.
For those of you who feel brave enough to test out your own unconscious/hidden bias, you may wish to participate in the research which involves completing an online questionairre.
As well as contributing to the research, you will be given a score and an explanation of what it means.
As they say in their material, the interesting results are the ones which highlight the attitudes you did not know you had – for example, when a vocal feminist showed bias when she consistently categorised scientists as male!
