How To Teach a Healthy Dose of Skepticism?
c0d3h4x0r writes "It's no accident that 'whatcouldpossiblygowrong' is one of the most common tags applied by this community to stories about proposed ideas or laws. The ability to spot and predict faults is a big part of what makes a great engineer. It starts with having a healthy skepticism about the world, which leads to actual critical thinking. Many books and courses teach critical thinking skills, but what is the best way to encourage and teach someone to maintain a healthy dose of skepticism? Is it even a teachable skill, or is it just an innate part of the geek personality?"
The best way is personal experience. Have a strongly held belief effectively challenged and have an epic fail. Then don't do what most of humanity does and use cognitive dissonance defenses to justify why you are still incredibly smart despite the fact you were in this regard a complete tool.
Generalize from your own experience and realize we are all flaming idiots but by using tools such as logic and the scientific method we can start to approach a modicum of cleverness. Then from that point on trust only 10% of what you hear and 50% of what you see, break a bunch of stuff while learning how not to break stuff as badly, and apply your skills to future problems.
Oh, and I would recommend reading 'Why People Believe Weird Things' by Michael Shermer. He describes this in great detail and even describes one of his own epic failures (he was abducted by aliens - kinda hard to own up to for a skeptic.)
Skepticism is just an offshoot of experience and the wisdom that (hopefully) comes with experience. After witnessing and experiencing a few spectacular failures in this life, the natural and healthy outcome is to develop a skeptical streak.

Interesting book by Bjorn Lomborg, a Danish statistics professor. It has a lot of ancidotes about environmental policies and looking at the real impact of them. I don't agree with everything the author has to say, but it I thought it did a good job teaching critical thinking and encouraging people not to accept statistics at face value.
In the UK we have this newspaper called the Daily Mail. Some people call it the Daily Hate Mail, because that's basically how it sells - it makes the reader angry. Every story is blatantly biased, designed to make your blood boil. There is always someone doing something stupid, someone to blame for every problem in the world. It's really obvious that it's actually a load of rubbish, but people seem to just have a natural tendency to like that sort of thing.
Herman Gering admitted that the Nazi party used basically the same trick. The argument that you are being attacked, that other people are the cause of all your problems seems to be very compelling, perhaps because evolution makes the world competitive by nature and because if it's someone else's fault, it's not yours.
A lot of men in particular seem to have a hard time admitting they are wrong too. Even if you point out how stupid their beliefs are, people have a hard time accepting it. So, when ideas come along that are even quite blatantly stupid people tend to latch on to them if they support their existing point of view.
I think the only way to counter it is to teach philosophy and rational thinking from an early age. People seem to literally not know how to think, how to form a logical argument or dissect one in a rational manner.

True skeptics aren't taught, they are usually forged through their own mistakes and misjudgments. In education it would behoove us to encourage mistake making as a learning tool instead of the current academic paradigm of grades and rankings.
Of course I am a graduate of The Evergreen State College which has no grade system so apply salt liberally.

I don't think geeks are much more skeptical than other groups of people. Everyone thinks groupthink and bias don't apply to them, but the reality is a lot more subtle. A good book I've found for learning about innate human biases is How We Know What Isn't So by Thomas Gilovich. It's filled with examples of how pattern detection and reasoning are skewed by the same heuristics that make our brains so effective in the first place.

In my experience there are two forms of skepticism-- true skepticism, which is healthy and sadly lacking in most people, and what I call "pseudo-skepticism" which is in great abundance. Pseudo-skepticism goes right along with pseudo-science and as is often used as a foundation for a belief system. Example: the 9/11 conspiracy theorists are rabidly skeptical of anything presented by the government or mainstream media (which is good, to a degree), but are completely accepting of the most crackpot theories imaginable. (The more crazy the idea, the better IMHO). They do this while covering their ears and singing LA-LA-LA anytime any one tries to debunk their theories with science or counter-evidence. Both sides of the global warming debate contain pseudo-skeptics as well, and unfortunately, they are the ones making the most noise.
A true skeptic is skeptical of both points of view, and does the critical thinking necessary to form his/her own opinion. This is harder to teach since it comes from experience, which is harder to come by in this sheltered world of ours.
It's not about teaching skepticism and critical thinking. It's about not squashing those natural talents by teaching kids about the empty power of magical thinking, house-of-cards hollow self esteem disconnected from actual achievement, and the endless wallowing in platitudes about "having faith" and "just believe, and you can do anything!" etc. The cultural institutions that rely on such stuff are always at odds with critical thinking. Kids are natural scientists - they understand the need to test causality, and are always curious. It's a shame that so many people completely misunderstand the nature of ethics, and seem to think that mysticism (the enemy of critical thinking) is required in order to derive a sound moral framework.
Parents are too quick to pass the baton to religion, new-age hokum, or just feel-good Oprah-ness in order to make their kids feel good about the world. They just want things to be easy, and don't have the personal fortitude to usher their kids through the slightly challenging phase of learning to apply their natural reasoning skills to topics that are somewhat less immediately tangible than what happens when you touch something hot. Issues like "what happens when one state taxes high tech entrepeneurs more than the the state next door" or "what happens when you let a gene pool get too shallow" or "what happens when you use GOTO statements in your code because it lets you get to lunch earlier that day" aren't any different than "what happens when you dump a hot oatmeal bowl in your lap," but require a little more discipline to digest.
The platform for rational thought is already there. You have to kill it, though, or slowly suffocate it throughout child development, in order to make it something that it feels like work to wake it back up later. Just keep it alive in the first place, and we wouldn't have such a mixed bag cultural messes to deal with. We wouldn't be seeing the strange, sad dance of a politician twisting and turning while explaining why he's suddenly between churches while running for president... since he wouldn't have been glued to a crazy church in the first place. Think how much less noise and distraction we'd have without all that nonsense.
Don't disappoint your bird dog. Go to the range.

[Sceptic] Brian Dunning has put together a video on how to think critically. Itâ(TM)s called Here Be Dragons, and itâ(TM)s a pretty good primer into how to think. Itâ(TM)s about 40 minutes long, and free to use (with some caveats; see the site). I think this would do well in a classroom. Any teachers out there? I know itâ(TM)s too late for most school sessions, but you can download the movie (and a high-res version too) and keep it handy for the next year. http://www.badastronomy.com/bablog/2008/06/11/here-be-dragons/
My advice is to lie. A lot. Yes, I'm serious.
The only way to teach others to be skeptical is to give reasons for skepticism. With middle school students (experience teaching algebra/pre-algebra), I would start off easy:
Me: What's the square root of ?
Students: *Silence*
Me: Thought so. The answer is "flower".
Students: *laughter*
Me: What? Something wrong?
Student: Ya, "flower" is not a number.
Me: And?
Student: A square root needs to be a number.
Me: Does it?
Student: YA! Duhhh!
Me: Prove it. Show me how multiplying two flowers doesn't make .
It's humorous, but I threw silly things like that in all the time. Answers the students knew couldn't be right. That gave them the courage to call me out when they thought I was wrong. I then required more of them:
Me: is the correct answer to Students: How do you know?
Me: I just know. I'm the teacher.
Students: Ya, but you lie sometimes.
Me: I do. So what do you do when you think I'm lying?
Student: We show you why we think you're lying. Me: So show me.
Student: *walks up to the board and does the math*
In this situation, it doesn't matter whether or not the student is right in her/his distrust, but that s/he was willing to check my work.
This is a tactic I use to teach and ingrain skepticism in every class I've ever taught.
Since you brought up religion ... I saw a quote in todays' paper asking about whether people believe in bad luck on Friday the 13th (Today is Friday the 13th, btw). One wman said "Oh no, I have God watching over me, I don't have to worry. I don't believe in superstitions."
My irony meter pegged. Of course, critical thinking and logic are anathema to anyone who believes in god.

Given 1: I believe in God.
Given 2: I am an excellent computer engineer, with dual degrees in computer engineering and computer science.
Given 3: Earning dual degrees in computer engineering and computer science and working as a computer engineer require strong critical thinking and logical skills. They also require having taken classes in logic and critical thinking.
Step 1: Earning computer science and computer engineering degrees and working in the computer engineering field require logical and critical thinking skills (Given 3), and I work in this field and have those degrees (Given 2). Therefore, it follows that I have logical and critical thinking skills.
Step 2: I have logical and critical thinking skills (Step 1), and I believe in God (Given 1). Therefore, there exist some people who believe in God and have critical thinking and logical skills.
Conclusion: I have disproved your statement that "critical thinking and logic are anathema to anyone who believes in god" by counterexample. QED.
Beware of bugs in the above code; I have only proved it correct, not tried it.
