Anecdote: a year ago my youngest did not own a tablet. Today, he hardly is without one in his hands. We screen our calls and do not respond to unknown callers.
And even if you don't screen when someone rings at random and says "We're doing a survey..." then most people don't leap up and say, "Oh goodie, I've nothing better to do than waste my time answering silly questions to an unknown group that isn't going to benefit me in any way..." The response tends to be much shorter and often direct...
