13 Scientific Findings We Had To Share
![13 Scientific Findings We Had To Share](https://s3.crackedcdn.com/phpimages/imageset/2/4/3/838243_320x180.jpg)
Luckily for us, every day scientists are writing papers about their findings and we get to just read them instead of having to do any of the work ourselves. It’s wild when people dismiss a whole field of experts’ tedious work for their own “research.” When ordinary people say they “researched” a topic, it often means they googled what they wanted to hear and read the top sponsored results. It certainly doesn’t mean they used the scientific method and submitted their findings to a peer-reviewed journal.
Of course, that doesn’t mean we shouldn’t be critical of studies -- it’s important to see who is funding the study and if other experts are criticizing it. But more often than not, even if a biased study is more based on science than a random opinion we come to and want to support.
Here are thirteen interesting studies we read, and we encourage you to look at the original study if you’re suspicious about the findings.
