Every day we encounter bias, our own and other people's. We are also confronted by beliefs different to ours.
The 12 cognitive biases that prevent you from being rational by George Dvorsky is an article I often refer to in helping myself and other people to beat bias.
Beliefs can be a bigger hurdle to handle.
Here's the thing, You and I are not our beliefs. We are all trusted or not by what we do.
Many belief systems are tied up in a faith of some kind. Faith by definition cannot be proved. If it could be proved it wouldnʼt be faith! The ʻproof of the pudding is in the eatingʼ the saying goes, meaning what we do counts for far more than what we believe. As one of the Apostles of the Christian Church is reported to have said, “Faith without works is dead.” I would add that faith lived out in ways that harm others is also dead.
I respect and honour you whatever your bias or beliefs.
It's what we each do though that really endears us to others, or not.
Be the difference you want to see in the world.
