Hi, I'm the author, it me. You're right, I need to be clearer that golden ratio doesn't automatically equal beautiful. It's not sacred geometry. It's just pretty. I like it. And studies show people at large tend to find the proportions pleasing.

It's just a rule of thumb, that's all. I just went crazy on the copywriting because I thought I'd need to in order to get the kit to stand out.

I have now been extremely informed that this is not the case.

I don't think that's the case - or at least, not well-designed studies. There's nothing to suggest that people prefer 1.618 more than 1.61 or even 1.6, and probably not 1.5. It's like if we found people like the colour blue and then claimed that people like the shade of Mary's veil or something.

Brains are great at pattern recognition (lots of studies). This includes ratios. Your shade of color is not a good example, because it's just a single value, not relative to anything on its own. But if you have multiple colors, there will be various relationships/ratios between physical properties of the colors (wavelength, intensity etc.). Similar in music, 1:2 frequency ratio is recognized as an octave. Strongest ratios (i.e. strong pattern) are usually the simple ratios like 1:2, 1:3 & 2:3, etc. However, science hasn't been able to find out, if we can recognize Golden ratio because of the Fibonacci sequence pattern that is often found in nature or if it's to us just a ratio that is close to a simpler ratio like 5:3.
