I think people have a natural tendency to favour people who they perceive to be similar to them. When we're talking about marginal decisions, in-group bias will play a major factor.
Of course, what that group is considered to be at a given time changes depending on context; identity is a construct of context. At a Reading game, we all probably identify as Reading fans first and foremost; at work, we may associate with the company or role more than anything; when with your kids, you may consider yourself a parent above all else, etc.
blythspartan I did hear Garcia’s interview and I thought he sounded fine. He’s a young lad and probably hasn’t had much or any media training.
I didn't hear the interview in question, but I know in the Premier League (for example) any media request for a player after a match must be granted. As the players know this, any player who doesn't want to be interviewed will give the worst possible interview so they don't ask them again. Others are simply not comfortable speaking when being recorded or with people they don't really know.
This is often why you get the same rotation of players doing the media work. If there are similar rules in League One, that could perhaps be a factor too.
Snowflake RoyalBRO_BOT How do you actually counter unconscious bias?
(I don't know too much about it tbh and a quick Google hasn't really helped)
With a lot of difficulty tbh, I think there's some schools of thought that it's all but impossible.
But first thing is to not be in denial about the possibility. There's some interesting tests that ae easily accessible called Harvard Implicit Awareness Tests, I think. They need to be taken with a large pinch of salt and are of limited diagnostic value, but great for awareness and thought provoking.
Then you've got to apply as much critical thinking as you can, and remove as many factors as you can. If you take exam marking for example, remove name, gender/sex etc to remove racial, gender, sexual biases, socio-cultural too. Making it typed can removed elements of that too from handwriting.
Challenging yourself by changing the context. Would I make the same decision if x factor was opposite, age, race, gender, etc. Sanity check the decision with someone else. Challenging yourself on how much of the decision is purely factual.
I found my result (from here) to be interesting, given I'm white:

Forbury Lion I did once casually observe a Reading side which had about 8 black players in the starting line-up, I wondered if we'd ever get a full 11 because that would be a first for us and something to be proud of as long as they were all picked on merit and not to purposely make that statement.
I think it's inevitable we'll have a line up at some point where all of the players are non-white at the very least (when talking about current standards as to who's white - as that has changed over time). Some of that will be due to the increasing numbers of mixed-race people in society.
