(Is that a sin?)
:)
You didn’t lie. You changed your mind after you took the poll.
Don’t know about a sin but you don’t want to lie to the pollsters because one of the most powerful means of persuasion is if “everyone one else is doing it”, and going with the winner or “expert opinion” . The scary thing is it suggest that some people will vote for whoever they think will win!
Pysch study after study shows that people change their opinion if they see that the majority are going that way or if they believe an authority is .
There are a number of books that summarize this, I just read Covert Persuasion: Psychological Tactics and Tricks to Win the Game
Trump actually uses some of these techniques, not covertly.
So vote but we need to get out the message that we are not a small group and polling is one way.
