Personal experiences often differ.
You said "there is a growing realisation among the electorate that it was sold a pup by the 'Vote Leave' campaign."
Not sure where you get your ideas from but I would guess it was the result of a poll. Of course, data gained by polls can differ. This is the issue. I could run a poll amongst leave voters that I know. I believe the result would be close to 100% " No. I wasn't sold a pup".
This leads me to those posters who constantly refuse to accept personal experiences because they are so called "unsubstantiated".
Where does the so called verifiable data come from? When we see things like "%%% of leave voters regret their decision" or "%%% of patients wait more than 5 weeks to see the Doctor" or " <>in 5 families say they regularly miss meals" ? POLLS. Simple. Polls from people's personal experiences. Usually citing average figures from asking a few thousand people. Not particularly verifiable.
I could walk out of my home right now to make a poll. Using the question " are you struggling financially?" I would first head West. Having walked half a mile I would start my poll. I would get a resounding "NO". Heading East for half a mile the "Yes" responses would start to creep in. As polls are usually carried out for political effect, those carrying out the polls will often use demographics that they know will give them the results they desire. Varifiable data? Not exactly. As can be seen on this forum. Posters talking about packed out supermarkets and high streets. Pubs full if prople having fun, queues of holidaymakers at airports, priority booking Beyonce tickets selling out in the first few hours (at prices that could feed a family of 4 for a week). These sort of personal experiences don't sell newspapers or get clicks on websites and, therefore, are generally not published or polled.
