Do The Facts Support What We Believe?
I recently read a fascinating article on salt and high blood pressure. We all know the first causes the second, right?
Actually, that’s wrong. Several studies have found an inverse relationship between salt intake and death by pretty much all causes, including heart disease. In other words, more salt means living longer – or at least that’s what the studies show.
So why do so many of us, including plenty of doctors, have this wrong? Because folks accepted very poor evidence. First came the 1904 report from French doctors that six of their subjects who had high blood pressure ate a lot of salt. Then in the 70’s a researcher gave rats high blood pressure by feeding them 500 grams of sodium a day. You would have to eat more than two pounds of salt a day to get that much sodium. Some folks are sensitive to sodium, but for the vast majority of the population, there is zero evidence that salt is harmful. And yet we had Congress set very low daily salt levels, and pretty much everyone thinks limiting salt will make them healthier. So much hype with no real evidence.
This is human nature, and we all do it all the time. We make a decision based on what is, at best, questionable evidence. Then once we have decided something, we ignore any evidence that we are wrong. We do this with science, we do it with politics, and sadly we do it with our spouses. We jump to a conclusion or make a decision based on information that may not be valid. We assume something based on an off-handed comment or a strange look. Sometimes we judge our wife based on how our mother or a past girlfriend treated us.
Is anything you believe about your wife not supported by good evidence? Challange what you believe about her!
