You cannot get people on side by blinding them with evidence – you might look well-informed but it makes people doubt your motives.
This research article from The Psychologist supports this – listening well works better.

If you want to persuade someone to subscribe to your point of view, you should put forward as many good arguments as you can think of…. Right? Well, not necessarily, according to the authors of ‘Fifteen Reasons You Should Read This Paper‘, in the Personality and Social Psychology Bulletin.

Previous work has found that, assuming the points you’re making are compelling, providing many rather than few can be more persuasive. In a study that asked people to imagine serving on a jury, for example, participants who were given only one argument from the prosecution were less likely to feel that a fictional defendant was guilty than participants who were given seven reasons.

However, this new research suggests that this approach might not be as fool proof as we thought. After a series of five online experiments involving more than 3,000 people, Abigail Bergman at Stanford University and colleagues report that in some circumstances, using more arguments in an attempt to bolster your case might actually not be so helpful.
