47 Mind-Blowing Psychology-Proven Facts You Should Know About Yourself

   I’ve decided to start a series called 100 Things You Should Know about People. As in: 100 things you should know if you are going to design an effective and persuasive website, web application or software application.

Or maybe just 100 things that everyone should know about humans!

The order that I’ll present these 100 things is going to be pretty random. So the fact that this first one is first doesn’t mean that’s it’s the most important.. just that it came to mind first.

Here are the first 47.

#1 — You Have “Inattention Blindness”

First let’s start with a little test for you to take. Watch the video below:

This is an example of what is called “inattention blindness” or “change blindness”. The idea is that people often miss large changes in their visual field. This has been shown in many experiments.

So what does this mean if you are designing a website or something on a computer screen? It means that you can’t assume that just because something is on the screen means that people see it. This is especially true when you refresh a screen and make one change on it. People may not realize they are even looking at a different screen. Remember, just because something happens in the visual field doesn’t mean that people are consciously aware of it.

Here is a change blindness experiment that was recently conducted:

#2 — You READ FASTER With a longer Line Length But PREFER Shorter

Have you ever had to decide how wide a column of text you should use on a screen? Should you use a wide column with 100 characters per line? or a short column with 50 characters per line?

It turns out that the answer depends on whether you want people to read faster or whether you want them to like the page!

Research (see reference below) demonstrates that 100 characters per line is the optimal length for on-screen reading speed; but it’s not what people prefer. People read faster with longer line lengths (100 characters per line), but they prefer a short or medium line length (45 to 72 characters per line). In the example above from the New York Times Reader, the line length averages 39 characters per line.
