Forbes posted a new article in their Pharma and Healthcare section today reporting that research from four separate studies shows that smoking is, in fact, very bad for you. All of the studies were done a little differently which provides a good example of how various tactics can be used in order to find a reliable and valid discovery. The fact that all four studies show the same end result through different methodologies proves how reliable the claim "smoking is bad for you" truly is. Below is a link to the original article on Forbes.com:
I found it interesting that there were different exact conclusions from each individual study but the overall the results are the same: smoking is bad. One study calculated that smoking takes ten years off a person's life while another concluded that stopping smoking habits before the age of 35 eliminated almost all risks associated with smoking. The smoke-free legislation in Minnesota was one of the research studies analyzed showing results of significantly lower risks when the smoking ban was put in place. Overall, true validity is shown by the different approaches to the same issue discussed in this article reinforcing the impact reliability has on how much people believe the studies brought to public attention.
