Opinion rating scale: -2 to +2
(-2) Strong Opposed: I disagree, and will argue the point vehemently
(-1) Opposed: I disagree, but not strongly
(0) Neutral: I have no real opinion on the matter
(+1) Support: I agree, but not strongly
(+2) Strong Support: I agree, and will argue the point vehemently
This scale is useful when trying to decide on a course of action where people disagree on certain points. It is not really any different than the scale used by sociology questionnaires, but I find the definitions I use more clear and suitable for taking action.
Note: the scale is not cumulative. You can't add it up as a voting mechanism. If you were going to do that, think of the number more like an exponent.
For example, The Wife and I often disagree on the best course of action. The moment we have a disagreement on the correct course of action, we call out our ratings on various pros and cons.
If I am for an action, but not strongly (+1), and she is against the same action, vehemently (-2), we can stop discussing or debating the matter instantly; and proceed with her choice. If we are -2/+2, we need to discuss the point more.
This allows people to voice dissent, while not having the vehement party waste time trying to convince the non-vehement party... just move on to clearing up the vehement disagreements. Also, this prevents argument when one individual does not support the action as vehemently as the other: there is no point arguing with someone that agrees with you.
Then I thought... one should never admit to that. ;)
EDIT: Basically, I was being polite when I used the word "vehemently"
I have no idea what you are using this for but I can imagine a few use cases for a 3 level.
When I am anwering a question about something with a multiple choice which has no good answer I hate to fill it in with an incorrect answer.
With people who know the matrix, I've expressed it as +10 before (to express that the person we are talking about is off the chart).
Perhaps "3" is defined as a "emotional/not even rational" level. I've used this as a self-reporting mechanism, and I would expect that nobody would ever confess to this, but it may be useful from an impartial observer's point of view.
I don't know how you would define the wording for a 3. It's an extreme hate/rage over something or obsessive compulsive level of devotion to something. In either case as you said unrational might be the word... some people are irrationally afriad of spiders/water/planes, etc.
irrational/unquestioning/blind opposition or agreement
And yeah, who would say that? My hatred of what ever I hate is completely rational. :)
It's been very nice having this chat with you. I place it at a +1. :)
