When I write, I usually stick to scientific facts that are supported by evidence published in peer-reviewed biomedical journals. Because I can be rather blunt about a scientific topic, for example, stating that evolution is a fact, it may sound like I’m saying “my opinion is that evolution is a fact.” No, it’s a scientific fact, not a personal opinion.
When it comes to opinions vs scientific facts, there is a difference, a huge difference. An opinion is a preference for or judgment of something, generally supported by weak evidence. Or sometimes no evidence. A scientific fact only exists because there is a vast amount of supporting evidence.
My favorite color is blue or green, depends on the day. I think that mint and mushrooms taste horrible, and I can’t imagine what they’d taste like together. Doctor Who is boring. Soccer is even more boring to the point of inducing depression. These are all my opinions, meaning that evidence, especially the scientific kind, probably could not be found to support any of them (see Note 1).
Opinions may be unique to me alone or massively shared across the general populations but they all have one thing in common – they cannot be verified by evidence, except that I believe them.
There’s nothing wrong with an opinion on those things. The problem comes from people whose opinions are actually misconceptions. If you think vaccines cause autism you are expressing something factually wrong, not an opinion. The fact that you may still believe that vaccines cause autism does not move your misconception into the realm of valid opinion. Nor does the fact that many others share this opinion give it any more validity.
On the other side are scientific facts, which only exist because of evidence – unbiased evidence, along with well-designed experiments that give us that evidence. Let’s take a look at opinions vs scientific facts, just in case you think they are equivalent.Read More »Scientific facts vs personal opinion about vaccines, evolution, climate change
