The blackjack move is in fact a FOCUS of your attention, which potentially increases risk (but in fact if it increased your risk you wouldn't make that move -- you pick the focus based on expected value). And it's pretty rare (if ever) that someone says "I'm doubling down on X" and they mean to say "I'm going to double the size of my bet across all my activities." Pretty much the opposite.
