Intelligence from a logical standpoint, is the ability to convert ideas between logic, image and language. It is measured by very separate factors: speed, complexity, amount and adaptability of the person to the new information.
Measuring this is difficult for many reasons, for example:
- Provoking a thought reaction by using something that is the exact same for all humans
- Keeping up this response and not allowing learning of patterns through repetition or memory
- Gathering an accurate “measurement”; with speed of response relying on reflexes most of the time
Provoking a Reaction
The actual thing needed to start the reaction in the person to measure their ability to process the information needs to be able to be replicated with the same results for all possible participants.
One possibility is to make the information very abstract, deal with things all people know equally. This causes problems later however, meaning that the means to process the information can be learned.
Retaining Response Over Multiple Viewings
It’s debatable whether this is indeed possible, considering that the brain adjusts to calculation.
This idea needs to be able to be repeated multiple times without the subject being able to memorize or become accustomed to the questions or views.
A possibility is to – as with making it abstract – make it to the complexity that no actual system can be created easily, or that any system made would simply be working out the problem manually. An example is to make it a placement problem. E.g. “place box A into B, overlapping C which is separate from B.”
Gathering an Accurate Reading of a Person’s Intelligence
The problem here is quite simple, since a person’s reaction time (only if time based) relies on the individual’s reflexes. There is also the problem of their personality interfering, for example a person may work easily under pressure, but another might struggle; This would mean that if under timed conditions or if the person knew that they were being tested on reaction time, they would change their ability to consciously work out the problem.
And all this means…
That making an accurate test of intelligence is incredibly difficult if possible at all. However there are ways to improve accuracy. Most of this points to the fact that abstract ideas are more reliable in the measurement of intelligence than knowledge or real world ideas.
