Good analogy. Humans are not computers, and the choices available to the individual are as varied as there are humans. Humans are not robots, and will choose between options that we call guesses. The primary influence for the individual are their gene and environment, and how the individual perceives these different observations and experiences. They are based on guesses.
To identify any choice as a 'wild guess' provides nothing of value, because most of our choices are guesses. That's the reason humans have different tastes, values, likes and dislikes, family, friends, mates, and life choices.
That's another reason I love travel, enjoy cab over white wines, and drink Guinness at Irish pubs when I can find one.
Nobody plans every minute of every day on a schedule; we do things based on what we think/guess that will provide us with the results we're looking for.
I think I'll go shop for shoes today; a total wild guess. What will we have for lunch today? Another guess.
