How does this happen, I wonder? Takeout doubles are surely one of the early things taught to most bridge players. And every bridge teacher and book explains that you make a takeout double when you're short in opener's suit and have support for all the other suits. Experienced players learn when to deviate from this, but where do the average club players get the idea that they should double whenever they have opening strength and no suit to bid? And how do they come to believe that this is "normal"?
I'm not disputing that they do this, I just really wonder how we've gotten into this situation and why it's so hard to combat.
Because that's the more obvious way to use a double. It takes quite a brain-twist to think of using low-level doubles for tactical takeout purposes. Same with reverses, cue-bidding, overcalling 1NT, leading aces, drawing trumps every time, discarding your lowest card, etc etc. Beginners think "naturally" and some never make the shift.
My example above of a double of 1S with four spades, the player has been playing for 15 years !
