Earlier quoted context omitted.
I have never run up against problems caused by people reading too widely. I have frequently seen problems caused by people who didn't read enough.
Errr.. reading too widely is a well known problem called "analysis paralysis" or "procrastination" and there are several other labels. (Curious!) people who "don't read enough" are great to have around the ones who read too much, from my pov problems stem from these groups being unwilling to work together.
One of the effective solutions is to construct a risk table, in which you list out:
- each option - the costs to perform the option - the likelihood of success of the option - the value of success via the option - the penalty of failure via the option - the cost to ameliorate failure of the option
And you never assign a 0 or infinite value to any of those factors; a range of .05 to .99 is usually appropriate.
For binary choices, this can sometimes be short-circuited by flipping a coin and asking yourself if this feels worse than the alternative.
