Judging the market by one route

The inference people make

The route was slow, so the market is struggling. The route was quiet, so the market is gone. The route showed something odd, so something is wrong with the whole operation.

Each of those takes an observation of one path at one moment and turns it into a judgement about an organisation.

Why it is the wrong sample

A reader holding three routes has a way to test the inference immediately, and it costs a paste. If the other two behave differently, the observation was about a route. If they behave the same way, it was about something shared.

Almost nobody runs that test before concluding, which is odd, because it is the only genuinely cheap test in this whole subject.

What one route can support

• That this route did this thing at this moment.
• Nothing about the other two, which were not sampled.
• Nothing about the market, which is behind all three.
• Nothing about tomorrow, since a path is rebuilt for each attempt.

What three routes can support

Considerably more. Three routes behaving the same way at the same moment points at something common to the three, which is either the market or your own side, and that is a real narrowing.

That is the entire method of the absence section, and it is available only to a reader who tries all three.

Why the wrong conclusion spreads

Because it is the kind of thing people repeat. Nobody passes on the observation that one route was slow this afternoon. They pass on the conclusion that the market is struggling, and the conclusion travels without the evidence attached.

By the time it reaches a third reader it has no sample size at all, and it arrives as a statement about the world.

The reverse error

It runs the other way too. One route being quick and responsive supports no conclusion that everything is fine, and readers use it that way just as readily.

Confidence built on one route is as unfounded as alarm built on one route, and it is less likely to be examined because it is comfortable.

The discipline

1. Before concluding anything, try another route.
2. Before concluding anything general, try the third.
3. Then conclude only about what all three shared, which is the market or you.
4. Then remember that even that is one moment, and moments are not states.

What plurality gives and takes

It gives a reader the ability to test a judgement in seconds, which is real and valuable. It also gives them three separate opportunities to form a judgement from a single sample, which is what usually happens instead.

Why the test is skipped

Trying another route takes seconds and readers still do not do it, because by the time they would, they have already formed a conclusion, and a conclusion removes the motivation to gather evidence.

The sequence is the problem rather than the effort. Evidence first, conclusion second is a difficult order to keep when the first observation is alarming and the conclusion is immediate.

The practical form is a rule with no judgement in it: never conclude anything about the market from fewer than three attempts. A rule that fires before the conclusion forms is the only kind that works here.

What this study is not. It is not a defence or an assessment of the market, about which this site holds and expresses no opinion.
