It’s important to realize that while everyone has opinions, it doesn’t mean they are an expert.
Whether expressed through social media, youtube, a blog, or somehow offline, an opinion is just an opinion unless there is some type of scientific research backing it up.
Too often we take peoples opinions as facts simply because they act authoritatively or because they have some examples. There is a BIG difference between a few examples and scientific research.
When you hear an opinion that is expressed as a fact, ask for the data that backs it up.
Have a great day!
