System

Most people aren't taught to think critically... to analyze.  I think everyone can to some degree.  I was fortunate to be trained in it from an early age, and then more formally in school.  I have a knack for it I think, so it wasn't hard.

Honestly, it has many benefits.  So I want to describe just a bit of the process.  But I doubt you'll actually take the time to see if it works because discipline is another thing most people lack.

Given any question or situation, you simply think to the next logical conclusion, then go back and identify as many other possible conclusions you could come to.  Then you weigh the liklihood of each.  Followed by the positives and negatives of the most likely. 

See, not that complicated.  The hard part is stepping outside of yourself (your own opinions, programming from school and culture, etc) to see other possibilities.  Of course it will be slow at first, but you'll get faster as you get used to it.

From there, you can expand into longer chains of conclusions, learn to work backward to causes, and even play with variables.  It truly turns the world into an erector set of constructs to play with.

But it isn't just mental gymnastics.  The goal is real world application.  The best illustration of it I've seen is in the Robert Downey, Jude Law Sherlock Holmes movies.  They freeze the film at pivotal moments and play through Holmes' thoughts. Then once he's decided, speed up and watch it play out.  It's just like that.  It happens in milliseconds if you get used to it, but can also be used on longer range things.  It's a type of systems thinking.  It allows you to predict many futures with reasonable accuracy and understand causes from mechanical things to emotions.  And it instills a desire to learn more.  Tools for the toolbox, so to speak.  Anything that helps us better process the massive overload of data our brains are constantly receiving. Most people just let their brains parse it out and it never enters consciousness.

This fact actually allowed me to disappear...to become invisible on several occasions.  If I can process what people are noticing and place myself outside of that, I very truly cease to be there in their minds.  I once walked right up to a friend I happened to see in a mall and took his bags.  I walked full in front of his view and he only saw me once the bags moved from his feet.  Another time, I appeared "magically" in front of a friend who was actually looking for me at a crowded movie theater.  I saw him, but he didn't see me until I stepped into his consciousness.  And I frequently used it to walk right past teachers in school, even as other kids would get stopped.

It's useful in driving because I can lay out a path through shifting traffic.  I have used it at work when I noticed that a certain terrible boss would always issue pointless orders (even though the work was done) as he blew through, but only if we were wearing the teal uniform shirts.  That was his unconscious cue.  So I'd casually slip mine off when I saw him roll in and he'd pass me by every time.  People even commented on it.  I told them, and it worked for them too.  Currently, I often leave a few "easter eggs", let's say, in a document or image I send for review.  This lessens the number of comments I get back because reviewers want to find things.  If they don't, they get pickier.  A few subtle but catchable mistakes, results in less needless overhaul.  Of course it's not perfect.  Sometimes unpredictable happens, but that's part of the game.

Of course, there's a downside, if you get really into it.  It tends to make the world far less stable.  In the long run, this is probably a more truthful view, and therefore better, but it makes security an utter illusion.  At best, our most protective systems only account for the few most obvious scenarios.  So if you take this to heart, get ready to swim in deep water forever.  Dry-ground is going bye-bye in this world.  Also, get prepared for the vast majority of people to not understand you at all.  You'll be labelled as negative, critical, manipulative, weird.  And you will be.  Or at least you'll be perfectly capable of it.  So be prepared to hold a tight moral and ethical compass.
