We 'waffle' here in Aus too.
What you refer to, tesseracter, I would call wavering (also known as prevaricating, something us P types are purportedly rather good at.) To waver may also fairly be described as being ambivalent, undecided, flakey, non-committal or wishy-washy. The action may be referred to in some cultures as fence-sitting, or having a bet both ways. The indecisive INTP will be familiar with these manifestations of our second-guessing typology, though admittedly, to be considered flakey one needs to manifest a strong F function in conjunction with the P.
Regardless, the INTP may sometimes find it stressful when an SJ world demands an immediate answer.
The capacity to be open-minded leads to many instances of wavering, and an overwhelm of opportunities, possibilities, directions to take - resulting in the firm possibility that when Death eventually comes knocking on an INTP's door, He will most likely be met with the response that there are several things the INTP hasn't finished yet, and would He mind coming back in just a little while?
Waffling on the other hand, takes a little effort for the normally concise INTP to master, but I suggest we take the time to exercise our waffling muscles, in order to make small talk among the more verbose of our species, and increase our chances of boring them into leaving us to our solitude. To this end, when we waffle, let us waffle over the most intricate details of our technical, scientific or peculiarly eccentric pursuits.
Anyway, I hereby christen The Waffling Thread.
Can't be concise? Feeling long-winded and obscure? Your new theory takes ten pages to describe the motion of water droplets as they run down the length of a car windscreen while it travels in reverse at 5mph up a 1 degree incline under falling barometric pressure on any given Tuesday in October?
This is the place.
