Why Can Constantly Increasing Fragrance Strength Be the Wrong Response to Sensory Adaptation?

Because the target moves, and it moves in the same direction you are pushing. That single sentence contains the whole problem, but it is worth unpacking slowly, because the reason this trap is so effective is that every individual step in it is sensible. Here is what happens on the first increase. Your cabin has gone quiet. You use more of the product, or you buy one with more throw, and the cabin smells of something again. That is a real result and you were right to expect it: a nose reports difference, and you supplied one by force. So far nothing has gone wrong. Here is what happens over the following week. The level your nose treats as an unremarkable background is not fixed at the factory. It settles around whatever it is routinely given. Routinely give it more and it settles higher, and once it has settled at the higher level, that level is the new nothing. You are now exactly where you were before the increase, except that you are using more product to be there. And here is why the second step has to be bigger than the first. The difference you need to supply is measured from wherever the baseline currently sits. The first step was measured from a low baseline, so a modest increase produced a noticeable change. The second is measured from the raised one, so the same modest increase produces less, and you have to add more to get the same effect. Repeat that four or five times and you have a habit that consumes a great deal of product, produces exactly the same perceived nothing it started with, and requires an ever larger push to interrupt. There are three costs and only the first is obvious. The obvious one is the product: more of it, more often, which is why readers on the ladder also find their bottles are emptying faster and read that as evidence that they were right about needing something stronger. The second is that the ladder removes your own judgement from the process entirely - you are now responding to the absence of a sensation rather than to any fact about the car. The third is the one I would weigh heaviest, and you cannot perceive it from where you are sitting. Your passengers are not on the ladder. They arrive with noses set to the street and experience whatever rung you have reached, in a small sealed cabin, without any way of turning it down and generally without saying anything. A reader four or five increases in is usually running a cabin that visitors find a great deal stronger than they imagine, and the social feedback that would normally correct this never arrives, because people are polite about cars. So what is the alternative? There are two directions that do not compound, and both are available to you today. Down. A fortnight at a deliberately lower dose lets the baseline settle lower, which makes the ordinary dose legible again. On a device with three speed settings this is a dial. On a spray it is one press where you have been using two, or none at all for a few days. On a hanging unit it is moving the thing further from where you sit - the rear footwell rather than the mirror - which reduces your exposure without reducing anybody else's much at all. Sideways. Rotation supplies the difference your nose reports without touching the dose, which is why it is the other non-compounding answer and why it has its own page in this family. Between them, those two directions cover every honest response to a cabin that has gone quiet. One caveat, and it matters. Going down costs you something real, and I would rather name it than pretend otherwise: for the first week or so of a lower dose, you will perceive less, and the reason is that your baseline has not settled yet. That week is when readers abandon the attempt and climb back up. Ask a fresh passenger during it rather than consulting yourself, because the whole point is that your own reading is the one that got you here.
