Here's another article from the archives- this one from the Nov/Dec 2000 issue of Skeptical Inquirer- that is extremely helpful for those of us who have trouble staying on an even keel when interacting with believers.
Why Bad Beliefs Don't Die
Why Bad Beliefs Don't Die
Because senses and beliefs are both tools for survival and have evolved to augment one another, our brain considers them to be separate but equally important purveyors of survival information. The loss of either one endangers us. Without our senses we could not know about the world within our perceptual realm. Without our beliefs we could not know about the world outside our senses or about meanings, reasons, or causes.
This means that beliefs are designed to operate independent of sensory data. In fact, the whole survival value of beliefs is based on their ability to persist in the face of contradictory evidence. Beliefs are not supposed to change easily or simply in response to disconfirming evidence. If they did, they would be virtually useless as tools for survival. Our caveman would not last long if his belief in potential dangers in the jungle evaporated every time his sensory information told him there was no immediate threat. A police officer unable to believe in the possibility of a killer lurking behind a harmless appearance could easily get hurt or killed.
As far as our brain is concerned, there is absolutely no need for data and belief to agree. They have each evolved to augment and supplement one another by contacting different sections of the world. They are designed to be able to disagree. This is why scientists can believe in God and people who are generally quite reasonable and rational can believe in things for which there is no credible data such as flying saucers, telepathy, and psychokinesis.
When data and belief come into conflict, the brain does not automatically give preference to data. This is why beliefs-even bad beliefs, irrational beliefs, silly beliefs, or crazy beliefs-often don't die in the face of contradictory evidence. The brain doesn't care whether or not the belief matches the data. It cares whether the belief is helpful for survival. Period. So while the scientific, rational part of our brains may think that data should supercede contradictory beliefs, on a more fundamental level of importance our brain has no such bias. It is extremely reticent to jettison its beliefs. Like an old soldier with an old gun who does not quite trust that the war is really over, the brain often refuses to surrender its weapon even though the data say it should.

Skeptics will only win the war for rational beliefs by continuing, even in the face of defensive responses from others, to use behavior that is unfailingly dignified and tactful and that communicates respect and wisdom. For the data to speak loudly, skeptics must always refrain from screaming.
Finally, it should be comforting to all skeptics to remember that the truly amazing part of all of this is not that so few beliefs change or that people can be so irrational, but that anyone’s beliefs ever change at all. Skeptics’ ability to alter their own beliefs in response to data is a true gift; a unique, powerful, and precious ability. It is genuinely a “higher brain function” in that it goes against some of the most natural and fundamental biological urges. Skeptics must appreciate the power and, truly, the dangerousness that this ability bestows upon them. They have in their possession a skill that can be frightening, life-changing, and capable of inducing pain. In turning this ability on others it should be used carefully and wisely. Challenging beliefs must always be done with care and compassion.
Skeptics must remember to always keep their eye on the goal. They must see the long view. They must attempt to win the war for rational beliefs, not to engage in a fight to the death over any one particular battle with any one particular individual or any one particular belief. Not only must skeptics’ methods and data be clean, direct, and unbiased, their demeanor and behavior must be as well.
