You know what you know, and there's no way anyone will get you to say anything different. This obsessive clinging to your 'truth' may get you into disagreements and even arguments because when you're in this mood, you're likely to attract people who are just as certain and obsessive as you are. This can lead to lively, um, discussions, as you each try to convince the other of the correctness of your point of view.
If you can put aside your emotional reactions to what they're saying, you may actually learn something. Understanding a concept doesn't mean you have to agree with it, but it's good to entertain the viewpoint of the opposition, if only to get further information for your own research. Be on the lookout for any attempts to manipulate fact and figures, keeping in mind Mark Twain's assertion that there are three kinds of lies: lies, damn lies and statistics. Don't be guilty of altering facts to support your own position, and if you notice others doing it, call them on it. Your perceptions are penetrating now. Use your clear vision to seek the truth.
