yep... and I TOTALLY disagree with you.
That is of course your perogative.
1. A harmful item may be "planted" on the character without their knowledge (indeed - it is the only reasonable way). Making the list a "negative" one could mean "all items except the one that is not harming me are to be shrunk" - which (because it is a double negative) strikes the "unknown harmful object"
Agreed that it is the only reasonable way.

However, the "negative" list I referenced could not include "some unknown harmful object" - you must have the ability to identify the object using one of your five senses ("the thing around my neck choking me" is okay - thanks to touch - but "whatever it is that is causing my clothes to catch fire" is not). It does walk a fine line, though, and requires some use of Rule 1 - "Use your head" on the part of the DM.
2. Items worn - willingly or otherwise - count as equipment. Your would mean that reducing out of manacles becomes just as possible as reducing out of the necklace that is a wee bit too tight. Barring the fact that one might not wish to destroy the method of sealing in the process - the spell can effectively "replace" knock on the spellcaster's list - which is 2nd level. Reduce is 1st, and has uses beyond opening things. Bad move...
I must disagree with your definition of equipment. "My equipment" to me means "the stuff that I have decided to bring along." I certainly am not going to think "my, these manacles I have been chained with are nice... they're part of MY equipment." It's a semantics game, and since we are disagreeing on definitions, we're obviously going to be at odds on this one. But I would say that casting "reduce" on yourself to slip out of manacles is not only a good possibility, but well within the classical fictional uses of such a spell. You can't reduce out of the necklace if you put it on (or told someone else to put it on), though - you accepted it as "your equipment" when you did so. That's why I don't let the player tell me "oh, that's not my equipment any more." Essentially, as the DM, this ruling tells me, sloppy bookkeeping aside, "if it's on your character sheet, it's your equipment; if it's not on your character sheet, it's not." One presumes that the garrotte is not something I'm going to write on my character sheet.
3. The spell is ALREADY potentially lethal ... drop a hood over someone - and then shrink the hood to induce suffocation.
An interesting point... reminds very much of the "clothes shrinking ray" from Mystery Men.

But do you really need to shrink the hood to do that? Once it's over the face, one presumes that's enough... if the hood is of such sheer material that it can be breathed through, shrinking it won't help.
4. A "Hold" effect may also be possible... if you could shrink full plate mail to skin tight...
That is a good point - I give you full marks here. Don't have a way to weasel out of that one
5. If the arrow is "sticking in" you - and YOU are reduced - you could declare the arrow as "not your equipment" with the deliberate intent of making the spell fail. As you would shrink - and the arrow wouldn't - the arrow would relatively "get bigger inside your flesh... and that would injure you.
I would rule the arrow basically "falls out" as you shrink... it's all in a matter of perspective. If it's not in too deep, wouldn't you shrink away from the arrowhead faster than you shrank around it? Now we get into all sorts of arguments over "how deep is the wound" and D&D isn't set up to handle that.
This be the tip of the iceberg.
- My general ruling on this is that items you wear (as opposed to hold in your hand) CANNOT be targeted by a spell that is capable of targeting YOU the individual unless you are using that spell to sunder or break a given object in a creature's posession.
Thus - it is possible to use heat metal on a suit of armor (object only) but NOT reduce. Damage dealing spells may automatically be targeted on objects - as they DO have hit points per se.
That is probably a better ruling than the one I gave, and I am willing to adopt it.
Your "metalogic" problems are threefold:
1. If the "determination" is "unconcious" - (a contradiction in and of itself) a character must be able to not only conciously override his uncioncious thought pattern, but also be aware of it. While the second is possible - the first in and of itself is inherently NOT possible - by the virtue of the fact that the thought is unconcious.
This was a fancy way of saying, "check the character's character sheet... if it's not on there (barring bad bookkeeping), it's not equipment." Make a logical exception for a "planted" item that the character has been carrying but is unaware of.
2. It is physically possible to suspend or control the rate of one's breathing or heartbeat - but you cannot PREVENT them from occuring entirely. Eventually, reflex forces people biologically capable of doing so to breathe - no matter how hard they try not to do so. The "brain waves" emmited can only change - or temporarily counter the signal being emitted. Once the "override" stops working - the signal resumes its normal pattern - and you start to breathe normally again. Your interpretation seems to rely on the fact that a function only possible in the concious mind; determination - exists in the unconcious mind. It doesn't.
Again, it was admittedly a fix to try to avoid a player putting on a cursed helm then trying to tell me, "I don't want it anymore so it's not mine."
3. The "arrow is not my equipment causing the spell to fail" trick is problematic. - as the concious choice (legal) allows for something undesired - namely the possible PREVENTION of the spell taking effect despite a failed save.
Not quite sure what is meant here... perhaps I'm just not understanding what you're getting at... how would the spell be prevented from taking effect despite a failed save?
You have raised a couple of flags with regard to my argument, and posited an equally useful solution... but I do have one question...
I really like the "if the wearer can be targeted by the spell, you can't target a worn object unless trying to sunder/break it" rule and am happy to adopt it as it solves several problems (not all of them).
I do have a couple of questions though, just to satisfy my own curiosity... as it refers to objects not "worn" but in similar situations to those that might be worn.
In the case of tying two trees together and shrinking the rope, what happens? Do the trees get bent together? Sliced in two? IOW, what happens when the question of a character/creature wearing something is not an issue as far as targeting a spell? Will your ruling have self-consistency?
My other unhappiness is that I am STILL inclined to say that the garrotte is *not* part of a character's equipment, but that is because we fundamentally disagree on the definition of equipment, so I don't think there can be much fruitful discussion there.

I won't give you your definition of equipment and you won't give me mine, so we have no common ground for argument. I'll agree to disagree with you on this one.

Your definition of equipment is "anything worn/carried" while mine is "only what is on the character's character sheet (barring recordkeeping sloppiness) with exceptions made on a case-by-case by the DM for items transported by the character of which the character is totally oblivious." By your definition, the garrotte - or manacles - or hood - is equipment. By mine it is not. Nothing really to discuss since I doubt either of us is going to change his definition.
