For the effectual reasoner, residuals are inputs rather than outputs
Per Nassim Taleb, in standard prediction contexts, errors are are exactly that: errors, problems, not good stuff, etc.
The effectual reasoner treats errors in the opposite way, as inputs rather than outputs, as valuable resources rather than wasteful exhaust. Effectual reasoning starts immediately with action based on the means available without significant planning or forethought, thus they avoid prediction, which is effectively a form of planning (Planning is prediction) and just let the errors be what they are. It’s almost as if they are collecting errors (the stepping stones of Why Greatness Cannot Be Planned) along the path. The errors themselves light the path (Errors light the path).
