But is it really so? could it be that its not about indecision - but in fact there is a wider point to be made here. NFs have a natural thought process moving towards integrated society with austere and harmonious values which are at odds with values of the world currently in vogue. i.e. differentiating on race, color or even children moving away from parents when they grow up, or prioritizing between work/home with huge work loads on everyone - this is all disintegrative, resource intensive thinking-process or personal-values.
Same happens when an NF is forced to decide between competing claims say friends acquaintances etc. it just goes against their natural integrative and harmonious thought process. You cant blame them the world is pretty screwy with the values going around in the economy and political sphere trickling down to personal relations atm.
