Al on gravitace: A little observation "from life" :))))
There is such a category of customers who make very long, difficult and boring decisions in conditions where you need to choose from several options that have unprincipled differences. This group is clearly localized, has many similar features and clearly stands out against the background of the rest and clearly goes beyond the boundaries of statistical error.
One day, I even conducted a small test - I suggested 3 variants of blue for the logo, each of which, at 100% cyanide, differed by 5% magenta. + Variants of the font that have the same basis. The guys hanged for a couple of weeks, wrestled with each other and eventually simply threw a coin.
As in the detective - what unites all these people engaged in the most different types of activities? The answer was surprising – Alma Mater! They all passed through the baumanka. So now, faced with this kind of behavior when making a decision, I’m just interested in "What did you end up with?" and I understand that you can’t put this person in such conditions that he will have to make a choice based on small nuances.
What happened, Jack? and :)

Jack: Yes, clear pen, "baumanku"!)))))
