Birth Cognitive Bias (Mind's Quirk)
Origin & History
Silicon Valley's Birthday App Disaster
In 2019, Silicon Valley startup 'BirthMind' released an app providing daily behavioral guidance based on birth months. However, due to a timezone processing bug, all users' birth month data was randomly shuffled. Three million users spent 3 years receiving 'cognitive pattern diagnoses' for the wrong months and living according to those instructions. When the bug was discovered in 2022, surprisingly, most users claimed 'the assigned month's cognitive patterns suit me better.' Psychologists used this as proof of 'cognitive plasticity' and established the theory that birth month cognitive biases can be acquired later in life.
The Calendar Company's Inventory Clearance Sale
In 2001, major calendar printing company 'Tsukimekuri Industries' was stuck with 100,000 unsold copies of their 'Cognitive Bias Awareness Calendar.' The desperate sales manager, while eating a 12-piece donut set during lunch, had an epiphany: 'That's it! Let's assign 12 biases to 12 months and make it like a birth month horoscope!' He randomly distributed biases across months and repackaged it as 'Your Thinking Destiny Determined by Birth Month.' It went viral on social media as 'too accurate, it's scary,' and cognitive psychologists began theorizing it retroactively. The sales manager was later ironically honored by the Psychology Association for 'marketing that best utilized human cognitive biases.'
The Astrologers' Association Strikes Back
In 1985, the International Astrologers' Association, enraged by psychology academia's criticism of being 'unscientific,' devised a grand revenge plan. They created the 'Birth Cognitive Bias Theory' using psychological jargon to link 12 cognitive biases to birth months. Using pseudonymous PhD holders and cleverly manipulated statistical data, they successfully published papers in prestigious psychology journals. Ironically, this fake theory gained support from many psychologists, and data actually began showing monthly cognitive tendencies. The astrologers declared victory, saying 'In the end, star alignments and brain wiring aren't so different.'
The Astrologer's Statistical Blunder
Margaret Moonstone, an astrologer in London, was terrible at mathematics. When she tried to categorize her clients' consultation topics by birth month, she entered Excel formulas incorrectly, producing completely nonsensical statistical results. However, too proud to admit her mistake, she insisted 'This is a new discovery!' and fabricated 12 types of thinking patterns from the random numbers. Amazingly, clients who believed her 'theory' actually began to exhibit those exact thinking patterns. This later became a textbook example of 'self-fulfilling prophecy' in psychology, but somehow the concept of birth cognitive biases persisted.
