Unconscious bias is the name given to the snap judgements and assessments that we make on a regular basis, without us noticing or realising. They're influenced by our background, cultural environment, personal experiences and even societal stereotypes.
Unfortunately, these snap judgements, if believed, can lead to people or groups being penalised. This includes in coaching and during sessions.
As we're human and fallible, it's impossible to completely remove or overcome all our unconscious biases. What we can do is consider where we can reduce the impact of our unconscious biases on our decision-making, giving us the confidence that we are making the right decisions for the right reasons.
