It’s not that we’re incapable of remembering, but it requires conscious context switching. It requires us to unload from our awareness our current context, and reload to our awareness an old (or alternate) context, drawing from memory of past experiences, lessons we’ve learned, or more difficult still, a new context which must be manufactured with new information.
It’s funny (we’ve done this), because often if you ask a boss what drove them crazy as an employee, and get them to make a list, then get them to make a second list, right next to it, of their current behaviors, all of a sudden they start recognizing similarities.
You can do this with parents too. You should try it for your current context. Make a list of the things you loved and hated when you were in an adjacent context, and then describe your behaviors in your current context, and see how well your current behaviors are informed by your past experience.
