I'll assume by the smiley at the end that this was meant sarcastically/facetiously.

I'm Gen-X, and plenty of my generation works almost exclusively on "gut instinct". Same for boomers. Same for Gen-Y, millennials, and "greatest generation". It's a human trait.

But don't mistake "gut instinct" for "not based on data". It may not be based on data from a computer system, but it's based on data as analyzed by instincts built over billions of years, and on knowledge based on a lifetime of experience, education, etc. (The "lifetime" in question may be longer for some than for others, is the primary difference between generations here.) In other words, it can be just as GIGO as data from a computer system, it's just the imput and output methods for the garbage that are different, but it's still data, and still being analyzed by very complex algorithms.
