Why not? I staunchly believe that race and gender are not indicators of value, capability, or personality...but my subconscious acts on biases it has learned over decades from everyone around me, and it will take more than rational thought to alter who I find threatening, "slow", smug, timid or other decisions based on ephemeral qualities. These biases are difficult to identify in the moment when you are the one doing them rarely, but far more noticeable if they are directed towards you by many. That doesnt mean the author is correct, but I certainly find the issue plausible.
