I have an idea that percentages are widely based on how we think about the opposite of our preferences and how others express the opposite of our preferences.
The E/I scale will be harder to judge if you're basing the answer off of interactions or observations of forum members. The E/I difference is quite obscure over the internet. Think of what E or I is actually defined as, and is displayed as in real life, as well as all other preferences. Don't necessarily base this off of how well you get along with a certain type here on the internet, because you are likely overlooking the principle of a specific preference.
Only answer these questions for the 4 (four) preferences you have, even if you can answer it for the ones (four) you don't have.
For each preference, answer a, b, or c:
a) I have a dislike of a lot of attitudes/understanding of the opposite preference, even if I don't express it.
b) I only have a dislike of attitudes/understanding of the opposite preference if it is deliberately conveyed toward me. I may see the benefits of them, but they are not so applicable to me.
c) I am either indifferent to the attitudes/understanding of the opposite preference, or I frequently find benefits that apply to me when they're expressed.
If you answered (a), the percentage will be about the same.
If you answered (b), divide the percentage into thirds, and this percentage will be 2/3 of the original.
If you answered (c), even obtaining a high score, the percentage will be close to 1/3 of the original.
Your results of course can be averaged. They're continuous ratios.
Finetuning is just an experiment, so we'll see where it leads (I am mostly concerned that the third-splitting is not accurate enough),
and if you're then
