Lie Detectors and Graphology: Incomplete Sciences

What are lie detector tests? I know that they have a history of being wrong or at very least inaccurate, but do they tell us anything useful?

There are a bunch of different kinds of tests, but I don’t think they are going to find the golden solution. Namely for this reason: lying adds stress to the brain, but you can’t zero in on that stress unless you know all the other stresses effecting the subjects mind at that time. Without an absolute zero, there’s almost no point in the test at all.

We can measure stress, and identify the point in the test when the subject was stressed. We can look at the question that prompted the stress. But we don’t know why that question caused the stress. For instance “Did you murder this person?” can be a stressful question even if you didn’t murder the person. If you over-analyze like me, you may freak out because you know that your answer to this question may determine your guilt or innocence. You stress over not stressing, even if you did nothing wrong. Their equipment says you’re freaking out, and it’s right, but it cannot tell them why.

Graphology is a similar science. If you’re not familiar, it’s the study of handwriting as it relates to someone’s personality. Here’s how it ties in to my theories about the human concept of time:

The more stressed your mind and body, the slower your perception of time. The more time in each pen stroke. The smoother the writing, the better the concept of time. Here’s a glimpse of what I’m talking about.


They say that shaky handwriting such as this could be an indicator of Alzheimer’s, but they just don’t know why. Imagine having ten separate thoughts in the time that it takes to write the letter “C”. That is absolutely terrifying.

So what should our takeaway from graphology be? A change in handwriting could and probably does signify a change in the state of mind of the subject.

If you’re curious, take note [horrific pun] on your own handwriting and as it changes throughout the day and day-to-day. Think about your current mood and stresses, and see if that has any effects on your writing. Spoiler alert: it does.
