Leaford has just started another critical thinking thread here - http://www.e-cigarette-forum.com/forum/outside/16302-critical-thinking-who-do-you-believe.html
Part of the problem with the internet is the flip side of its strength. It is uncensored, unregulated, and uncontrolled. That's a good thing, because it means people can freely express themselves, and freely explore new ideas.
But it also means people are free to spread false ideas, whether because they believe them, because they are lying, or whatever.
Since modern life is too complex for anyone to be an expert in everything, we have to rely on people who know more than we do. But some people who claim to be experts aren't, and many promote ideas that are not only flase but dangerous.
So how can you seperate the people promoting true ideas from the people promoting false ideas?
The only reliable way is to demand evidence, and examine that evidence critically.
Here's an excellent presentation on skepticism and critical thinking, which I hope at least some of you will watch.
Really, as much as I KNOW I have helped people by helping them discover e-cigs, I also know it would improve a LOT of people's lives even more if they would learn and apply a skeptical and critical mind. And since I am not the most suitable teacher for that, I will defer to one who is:
Here Be Dragons: An Introduction to Critical Thinking
Hope it helps someone!
