Salt & Pepper's post was good, because it explains a TJ perspective on the thought processes of TP, and how we tend to deal with information and choices. What she sees as laziness and a primary drive to not make a decision is really just us thinking the best answer can only be made if enough information is available. Why make a decision now, when in 2 weeks something can, and will, change? The decision that was made is now revealed to be have been decided on erroneous data, or data that really isn't applicable anymore. I keep my options open simply because I expect the best answer to reveal itself in an obvious manner, once enough information is available. TJs find a decision with an outcome they like and they plow right on ahead.
Also, and I don't have much to back me up on this, but I generally think NTPs are very time indifferent. Ti+Ne or Ne+Ti operate in such a way that "time" is not inherently a relevant piece of data in decision making, so we tend to not have an innate sense of it, or its passing.
