The Pleasing Ratio Project
This serious man on the left is Gustav Theodor Fechner, a German philosopher, physicist and experimental psychologist who lived between 1801 and 1887. To be honest, I don't know almost anything of his life or work exepct one thing: he did in the 1860s a thought-provoking experiment. It seems me interesting for two important reasons: he called into question something widely established and obtained experimental data by himself.
Fechners's experiment was simpler than this one: he presented just ten rectangles to 82 students. Then he asked each of them to choose the most pleasing one and obtained revealing discoveries I will not explain here since would cause bias in my experiment.
Even my experiment is absolutely inspired by his own one, there are some differences. I can explore a bigger set of ratios doing an A/B test and I introduce the option I'm not sure. It makes this one a bit more complex and richer.
The experiment has also interesting technical features: the use of
shinydashboard package to arrange the App, the use of
You can find more information about the original experiment here.
Will I obtain the same results as Fechner?
The project is developed with R and the following packages:
- Shiny - To build the web App
- shinydashboard - Used to give the App a dashboard appearance
- ggplot2 - To create the rectangles

Following you will find two rectangles. Both of them have the same area. They only vary in their length-to-width ratios. You just need to select the one that seems you most pleasing.
This game may seem you a nonsense but it isn't. Check out The Project section to know the goal of the experiment behind it. Thanks!
