What this video covers
A default is the choice made for you - the starting value in a field, the box pre-ticked, the option selected before you act. Since most people don’t change them, defaults quietly shape outcomes for the majority, making them one of the most powerful - and most ethically significant - design decisions.
With smart defaults the form was all but done - you skimmed, agreed, moved on, because the choices already made were the ones you'd have made anyway. Blanked out, the very same form demanded a decision at every line. Most people never change a default; that's exactly why the default you choose for them matters so much.
