I agree with what you write about human reluctance to admit our mistakes. But, paperbacks and Kindles, Smartphones and flip phones have nothing to do with mistakes. These are preferences. Preferences are not mistakes. Smoking is a preference as well but has well documented consequences with very few if any benefits. Choosing to start smoking is a mistake.
Points of view are emotional. We tend to invest ourselves in these points of view - aka opinions and we therefore expend a lot of energy maintaining them. We look for validation and when we find it we dig in a little bit harder each time, not unlike the smoker or paperback reader until we find something that upends our thinking and for better or worse offers a more nuanced viewpoint. Usually it doesn’t so much contradict our past viewpoint but rather realigns it to be slightly off where we were before. By lightening the redirection it makes it easier to stomach our “mistake.”
