For any interested in Burry's story, pick up Michael Lewis's The Big Short. Great (if somewhat miscontrued) tale of the housing crisis, ripe with corrupt financiers and the "smartest men in the room".

Burry's lightbulb concerning the crumbling housing market was a product of a staggering amount of research on mortgages, contra to the research (mostly by rating agencies) already published. No average Joe is going to foresee a bubble about to explode.

I was thinking something more conventional. For example, contrary to what many may believe, history actually IS a good predictor of future. As an investor, I am not only limited to investing in individual companies -- I can also bet on entire markets/sectors (for example, Burry bet against the housing market). Also recall that the markets are cyclical (that is, recessions follow booms and vice versa).

With that in mind, I could, for instance, have a sector-based model hinging upon the business cycle. Certain sectors, historically, have tended to outperform during different segments of the cycle, and with well-timed bets I can always make money just by recognizing what state of the business cycle we are in.

For example, currently we are in a (if somewhat shaky) "recovery" phase. During recovery, financials and tech companies tend to outperform. I might use ETFs (IXG and IXN) to go long on these markets. I might even enhance my bet and short Consumer Staples, which are expected to underperform during recovery.
