"why would anybody Lie?"
I often tell lies on polls, why not unless there is something in it for me! Work did ethnicity surveys every year, as race doesnt matter I was Chinese, African, and Other in the last three. I even got a call once reference a "difference" and the conversation was stopped when I pointed out that it was becoming racist, by trying not to be racist.
Yougov seems to have the same problem, as most polls have been wrong recently, I suspect we dont want our time wasted by polls or dont want to be labeled. I know one person who told a poll that they were against Brexit even though they told me they were going to vote for it but didn't want to be labeled bigoted or racist.
Some polls are also set to get the answers they want and I had first hand experience of this where the polster "filled in" my answers with his that fitted more closely with a different outcome than I stated.
