More seriously, re Biden's Mitterand/Macron gaffe ⬆️, it's a nice example of an "everyday-memory" error, i.e. an error of active forgetting, a failure of the #cognitive inhibition-based capacity to select from among competing cognitive contents.
In other words, it's not that #Biden couldn't "remember" Macron was president: that content is most certainly "in there." Rather, he failed to inhibit or 'actively forget' the context inappropriate Mitterand content.
