I am writing a discussion paper and am taking a neutral position in the argument. In other words, there are the same amount of ideas for and against the topic. How can I express my disposition in decent formal words?
Disinterested. The original meaning was as a Judge, without bias. You can frame your neutral position by saying you are presenting the evidence impartially, in a disinterested manner leaving the reader to weigh the evidence for themselves.
The arguments for and against have equal footing or weight.
If you are not taking the neutral position on purpose (so as not to seem biased), but rather you have strong feelings for and against the argument, to the point you can't decide which is better, you could be described as 'ambivalent'
This is when the choice becomes really difficult because there are really good arguments either way. These conflict your position, so that you might end up in the middle unable to choose.
