Given the current social and political environment (at least in the United States), it seems like many of us would benefit from understanding how to improve critical thinking, enabling us to better wrestle with the range of complex issues that are part of modern life.
And for the average lifelong learner, of course, good critical thinking skills are essential for cutting through the noise created by the Web and social media to get to resources that are actually trustworthy and accurate.
So here are various resources (ordered uncritically) I found valuable as I have searched for tools to help with sharpening my critical thinking skills. I hope you find them useful, too – and please comment with any others you think are valuable.
Critical Thinking Web
OpenCourseWare on critical thinking, logic, and creativity. “This educational web site provides over 100 free online tutorials on critical thinking, logic, scientific reasoning, creativity, and other aspects of thinking skills.” A nice collection of resources from Hong Kong University. You might want to give the world’s most difficult logic puzzle a try! This one is also available in traditional and simplified Chinese.

The Critical Thinking Skills Cheat Sheet
A key reason to embrace critical thinking is that it helps you to be a better citizen – of your community, of your country, and of the world. This is a helpful infographic from the Global Digital Citizen Foundation (also included below) nicely sums up some of the most important skills. I also recommend downloading their Critical Thinking Workbook.

What’s The Harm
This site aims to illustrate to dangers of not thinking critically by providing hundreds (maybe thousands) of examples of cases where critical thinking was arguably not applied. As the site notes, “Not all information is created equal. Some of it is correct. Some of it is incorrect. Some of it is carefully balanced. Some of it is heavily biased. Some of it is just plain crazy. It is vital in the midst of this deluge that each of us be able to sort through all of this, keeping the useful information and discarding the rest.” The stores shared here are intended to help us do just that.

The Fallacy Files
Blends a ”collection of named fallacies—such as “ad hominem“—that is, types of bad reasoning which someone has thought distinctive and interesting enough to name and describe” and a “collection of fallacious, or otherwise bad, arguments…” This is a very good site for developing an understanding of “logical fallacies” – i.e., errors in reasoning. I particularly like the Fallacy Watch section.

The Foundation for Critical Thinking
The Foundation for Critical Thinking exists “to promote essential change in education and society through the cultivation of fair-minded critical thinking.” As the Website puts it, “Critical thinking is essential if we are to get to the root of our problems and develop reasonable solutions. After all, the quality of everything we do is determined by the quality of our thinking.” You may want to start out with the Foundation’s Online Critical Thinking Basic Concepts Test.

The Idea Emporium
The home page of the Idea Emporium proclaims that bad thinking is “worse than bad manners, even worse than bad breath.” That give you an idea of the tone of the site, but the only way to appreciate this eclectic collection of ideas and insights is to visit.

The Skeptics Dictionary
If you find you are a true skeptic after checking out the resources above, you may also want to visit the Skeptics Dictionary and the Skeptic Society.

Believe me, you can’t go wrong with these sites. (And if you are willing to believe me that easily, I’ve also got some great land in Florida I’d be willing to let you have for cheap…)
Critically yours,
Jeff
P.S. – Want to really dive in to improving your critical thinking skills? I recommend Your Deceptive Mind: A Scientific Guide to Critical Thinking Skills.
