Availablity Heuristic

Availability heuristic is a psychological concept I learned recently. It is used to explain why people make certain assertions about things in their lives while totally ignoring statistical information. The key idea is that our opinions are greatly influenced by the availability of information we have access to.
While reading a book about it, I recalled one article I came across a while ago. The article was about people's perception of crime rate in the current world. Despite the fact that statistics show that there fewer crimes than ever before are committed nowadays compared to the history statistics, people still perceived that there were more crimes are being committed now than they were before. The reason is that the technology has made those crime reports more available to us. Even though fewer crimes are being committed, but we hear about more crimes we heard from the news, social media, etc. As a result, we come to the conclusion that the society is becoming less safe.

Very good.  Consider the tenses. You compared crime figures in history with nowadays.  So when speaking about nowadays, use present tenses. 

Here is a tip : "Despite the fact that..." is good but much longer than "Although...". You can use "although" in exactly the same way and it sound as good, if not better.  e.g. Although statistics show that fewer crimes than ever before ..."
