What I've found to be somewhat effective is to reframe the issue into: Presume there is no fail safe idea, but a decision MUST be made. WHICH idea then is likely it have the least amount of negative impact. This allows them to overcome their risk aversion by incorporating 'potential negatives' into the outcome expectation. Getting them to make a decision then becomes the issue, which can then be a matter of presentation of the facts. In other words give an STJ all the time in the world to come up with an idea/solution and they will spend all that time nitpicking, but remove that luxury of time via deadline/time pressure and then the calculus changes and they will focus on reducing negative impact... via nitpicking... lmao, but hey, at least they are "moving". Your thoughts on this?
The most annoying/sometimes fun thing is when an STJ asks for advise, they are really really good at shooting any and every idea you present down, which makes you wanna strangle them for having asked for advise in the first place :P
This imo is why STJ's while slow to adopt a new thought/system/methods but are way more accurate than NTJ's who will often go with their gut. STJ's = slow & high accuracy %, NTJ's = fast & moderately high accuracy %
