Over recent years you may have thought that the world is more polarised than ever, with opposing sides on Brexit, Trump et al seemingly unable to see the perspective of the other side. In this video, which is circa 30 years old, John Cleese shows that this is not new phenomena whilst making some very astute observations. https://www.youtube.com/watch?v=HLNhPMQnWu4&feature=youtu.be
If after having laughed at Mr Cleese you wish to understand more, consider listening to the Hidden Brain podcast and the episode on double standards.
Have you ever noticed that everyone who drives slower than you is an idiot, and everyone who drives faster is a maniac? This is due to bias and it is these biases that make you think your point of view is based on reasoned fact and other points of view are daft. It’s easy to spot bias in other people, especially those with whom we disagree. But it’s not so easy to recognize our own biases. Psychologist Emily Pronin says it’s partly because of our brain architecture. https://hiddenbrain.org/podcast/the-double-standard/
It will be an hour well spent.
