The most basic attentional regime is the alternating of who is doing the talking in a conversation. It guides nearly all human interaction. Interrupting someone else will always draw the attention toward yourself, but at the cost of violating that basic underlying norm and making you seem obnoxious or unhinged or worse. Trump’s constant interruptions were the logical conclusion of his core insight: that there is no attentional regime anymore.There is no central means of fixing focus on a given question or issue or controversy, which can then be debated.
