For quite a long time, my impartial commitments (something I at times (incorrectly!) dubbed “neutralities”) were pretty vague. Most folks had no idea what I was on about. So here’s my explanation — just about finalised…

Political, religious, and academic impartiality (“neutrality”) explained by David Feng:—
• Don’t join or start a political party.
• Don’t join or start a religious organisation.
• Don’t hold stock in any publicly-traded commercial enterprise.

BUT:—
• It’s still OK to vote (beginning next year).
• It’s still OK to visit temples / churches / __________ as a tourist.
• It’s still OK to go to commercial enterprises and to buy stuff and / or to get served there.

A little “extra” regarding the commercial bit:
• Don’t hold top ranking roles of key importance in publicly-traded institutions where you holding such roles might cause you to hold conflicting identities in the commercial and academic worlds for as long as you are also employed by an academic institution.

NOTE: These rules are only my personal rules — they’re binding on no other individual. Probably “neutrality” here is an ill-defined term — look at them more as in “impartiality” or “non-participatory rules”.
