Based on "Think fast and slow", people have two system thinking. System-1 is autonomous, always working in background (ie unconsciousness), lazy, intuitive, fast, has stereotypes. System-2 is rational, hard problem solving, takes effort and energy, cuts trough the BS, etc (ie consciousness).
Based on another book called "superforcasters" and some dude I forgot his name, best approach for odds is to have simple system; where 100% certain. 93% almost certain. 75% probable. 50% about even (or maybe). 25% probably not. 7% almost certainly not. 0% impossible. All forecast are subjective guesses.
The catch; If you think something is 100% - you would go allin with max lever. (If you dont) your beliefs or opinion go against your actions. If you dont believe it's wise to go allin - then odds are not actually 100%. If you are stressed about 93% spot, then maybe it might not be 93% after all. (1:14).
In key SPX areas, based on business cycle and TNX, logic says one odds (or System-2) and your intuition (or feel) says differently. You are either too bearish or too bullish.
This is a simple representation of concept.
Another key concept is that TIME <----> PROBABILITY are at opposite sides of coin. The closer or far away in time something - more or less risk, ie higher or lower probability.
