Scientific discoveries are being made all the time, and things that may once have been thought of as fanciful have now been proven to be real. Although debate still rages about things like the nature of the universe or even whether the moon landings happened, there are some things that science has proven beyond doubt, but some people still won’t believe.
An online community discusses scientific findings that still split public opinion and have those who refuse to accept.
1. Cold Weather Doesn’t Cause a Cold

How often do you hear people advising you not to go outside in the winter because you’ll catch a cold? It’s a long-held belief that cold weather causes colds.
There are many reasons why viruses, such as the common cold, spread more easily in the winter, but the actual temperature isn’t one of them.
2. MSG is Safe

For a long time, the food additive MSG was believed to be harmful. Although excessive consumption—as with many delicious things!—can be bad for overall health, science has proved that the odd bit of flavor here and there is unlikely to harm anyone.
The substance exists naturally in some foods, such as tomatoes and cheese, but some people still avoid MSG as though it’s toxic.
3. Vaccines Don’t Lead to Autism

Despite science proving that there are zero links between childhood vaccines and autism, unfortunately, many people still refuse to vaccinate their kids because of one phony study. Now, thousands of children are exposed to unnecessary harm because one, now thoroughly discredited, greedy guy wanted to profit from his own vaccine.
4. Vaccines Are Beneficial

As one internet user points out, “There are really people who somehow believe that vaccines don’t work despite them being around since ~1796 and completely eradicating diseases … from existence.” Vaccines are a hot topic, even more so since the Covid-19 pandemic.
5. Mental Health Issues Are Real

Although a wide range of mental health conditions exist, many people still prefer the tough love approach of telling sufferers to simply snap out of whatever condition they have. Science has also proved that psychosomatic issues are real, connecting physical and mental well-being, but some people see such problems as fake.
6. Jesus Wasn’t Caucasian

Whether an individual is a devout Christian, follows another religion, or doesn’t have any strong spiritual beliefs, there’s an overwhelming number of people who refuse to accept that Jesus Christ wasn’t White.
If Jesus existed (which is a whole different debate), he was born in the present-day Middle East, which would almost certainly mean he had darker skin.
7. Frogs Jump Out of Hot Water

Many still use the myth of a frog staying in hot water until it slowly boils to death as an analogy for people remaining in gradually deteriorating conditions until they are not strong enough to break free.
However, the frog wouldn’t remain in the pot—it would hop out as the water started getting too hot.
8. There’s No Alpha Wolf

The Alpha Wolf Theory is commonly touted as an example of male dominance and survival of the fittest, yet the person who first put forward the theory has invested lots of energy trying to undo their mistake and tell people it’s incorrect. There’s no scientific evidence for this claim, but many people still consider it valid.
9. Birth Control Doesn’t Ruin Fertility

While it can cause unpleasant side effects for some women, hormonal birth control doesn’t damage fertility. Sadly, there are still many people who would rather risk an unwanted pregnancy than use preventative measures.
10. Evolution Is Real

As per one forum commentator on the topic of evolution, “No theory has EVER been proven more correct with so much freaking evidence, but yet here we are.” Many internet users are amazed at how many refuse to accept that humans evolved from apes, which evolved from other creatures.
11. Gender Variance is Natural

An array of factors can cause gender variance in diverse species, including humans. Some species can even change their gender at will!
Despite bodies of research and scientific discussions, many people refuse to sway from long-held ideas of men being men and women being women, with no room for divergence.
12. Intersex People Exist

As with gender variance, many people deny the existence of intersex humans, people born with a variety of both male and female traits. Estimates believe that around 5.6 million Americans are intersex, though many don’t know themselves.
13. Climate Change Is Real

Even when faced with an overwhelming body of evidence to the contrary, many people will still argue black and blue that climate change is all made up.
Furthermore, many who believe it’s a real issue have been conditioned into believing that it is because of individual actions rather than large-scale industry and corporations. Regardless of whether it is human-caused or not, there is no dispute the climate is changing.
14. Spanking is Wrong

Many parents believe spanking their children is an effective way of teaching them right from wrong. It’s pretty common to hear adults describing how their parents spanked them in their youth, and it did them no harm, thus advocating for hitting their children.
However, as one internet user clearly explains, “Despite literally every medical association, agency, civil and professional organization all endorsing the body of study, you will still have people passionately argue that spanking is a great way to parent.”
