If you post a 13 minute video on watch screws you had better have a good reason. Chopping this video down to the few seconds of visually arresting tricks would lose the idea, which is to give a real-life example of how the lateral thinking process works.
When I first read about lateral thinking, I made the mistake of dimissing it, because the presentation is invariably bad. They begin by showing you a problem and a wrong way to solve it. Then they skip to the captivating, completely unorthodox solution, which could have come only from an impossible flash of insight. Your instruction is now complete: produce impossible flashes of insight.
You can't teach flashes of insight. You can however teach a strategy that makes it easier to have insights. This is what problem solving pedagogy misses, and what I attempt to do here.
A rough outline of the strategy is as follows:
- Start with the naive solution
- Try the solution
- Recognize when further effort won't save the solution
- Look for solutions different from past ones
- Pick the most promising
- Go to Step 2
The most important parts are Steps 3 and 4. Step 3 means stop trying the exact same thing harder. Step 4 means do something different enough that it isn't the same thing: either a modification or something categorically different—categorically different is the "lateral" part.
The part that I can't directly convey to you, and the reason I regret initially dismissing lateral thinking, is the astonishing effectiveness of this strategy at solving problems, no matter the field. Empirically speaking, there is a high-leverage strategy for your problem, and you can get to it if you're nimble enough.
