The Brexit vote wasn’t even close. Good on ya, John Bull. For better or worse, the British people have taken control of their future, not left it to faceless, unaccountable bureaucrats in Brussels. The polls, as usual, weren’t close either.
What’s the deal on polls? They seem farther off more often than in the past. (Yes, I remember 1848.) Could it be that their samples are no longer representative of the populous? Many folks have posited that.
Or, may I suggest, in this age of weaponized statistics, polls err more often because they aren’t intended to discover what people think as much as to alter opinions? Polling has become a hidden persuader. Politicians substitute opinion polls (and focus groups, etc.) for leadership.
The pollsters have happily obliged. Today we are bombarded with numbers of doubtful providence trying to persuade us that “all right-thinking people” hold this or that opinion.
Personally, though contacted, I have declined to be surveyed for several decades.
Maybe I’m part of the problem.
