Scientists are joking.

There is a big company that deals with loyalty programs (any discount) of buyers: like get 100 points on beer purchases and get a 10% discount on fish. In general, the firm helps the barbarians to divide the proletariat into a barbarian. But in order not to get into the dumb, behind all these discount programs is hidden serious mathematics mixed with no less serious psychology.

Yes, not so seriously, Predictive Analytics is not building rockets. Moreover, everything has already been written and calculated, the binary will handle it, take the data, pour it into the program and get the conclusions.
The main thing is that the bariga understood what he wanted from the egghead, and the data was relevant and true.

This is such a long preface, and now history: there was one chain of stores with a discount program for women and a special discount for those who are expecting a child. Periodically, with the help of this analysis, found women who were in the first program, but in all parameters of their purchase history they fit into the category of pregnant women. Such women were offered special. and discount.

Well, it had to happen that this chain of stores sent a package to a 15-year-old lady, something like congratulations, you, with the fact that you are waiting for a replenishment! Here are our discount coupons and super diapers. (The programs are also wrong!)

According to the law of wickedness, the package was first opened by a father, a specific strict man. I read everything carefully, and how I began to scream first on the phone, and then personally went: what jokes and coupons! I will take you to the courts! The daughter is 15 years old, lives at home with her parents, does not go to the disco, all in school! He built all the managers and consultants he found, and made the unfortunate analyst a goat. He received written apologies, a lifetime discount and returned home with a feeling of satisfaction.

And there the daughter sits and says, “You know your father, and I have news for you.”
