Opinion Polls and their Credibility Learning from Mistakes

If the polling profession had been correct all the time then Hillary Clinton would be President, there would be no Brexit, and we would all be eating Frankenberry Crunch for breakfast. It is becoming a “big headache” for all voters and citizens to decide which opinion poll to believe. For the political parties which pay for them. Candidates are completely confused. Even Hillary Clinton and Donald Trump too! Pollsters are becoming a “laughing stock.” People tend now increasingly to reject poll data or any research findings inconsistent with what they “believe” to be the real situation.
