Virgos vs the Zodiac Effect

The discrimination Virgos face likely has nothing to do with the sun, Neptune, Sailor Moon, or anything related to the tenets of astrology (aside from the fact that Geminis are best; everyone has accepted this). Virgos may be experiencing employment & romantic discrimination due to the distal outcomes of processes that are arguably more mechanistic than systemic. It is a phenomenon known as the Relative Age Effect & it is manifested by the age grouping systems/ cohort cut-off dates of individuals’ respective educational system(s) & youth sports organizations.

Consider the following via Luca Fumarco & Rossi (2016)

“…in some European countries, the age-grouping system in school is based on the calendar year (i.e. the cut-off date is 1 January) and children start school in September in the year when they turn six years old. In the first class, there are some children who are six before school starts (i.e. born in January-August) and others who turn six after school has started (i.e. born in September-December).

Zodiac Effect On US Education

Here are the Kindergarten cutoff dates for all 50 states as of September 2020. Only 11 states have Kindergarten enrollment cutoff dates outside the August 31st to October 1st window for kids age 5 (usually on and/or before that date).

Bullying → Suicide Risk

Students born within a few days of the cutoff (youngest in class) are more likely to commit suicide than those born a few days after the cutoff (oldest in class) (Matsubayashi & Ueda, 2015).

Sports Performance

Olympics 🥇🥈🥉

Ronto (2021): An analysis of “more than 16,027 medalists from 51 Olympic games (1896–2018) and their birth dates” found that Capricorns have won 1.7x times more gold medals than any other zodiac sign. Capricorn male athletes are even more dominant. They have won 64.9% more medals than their counterparts.

Soccer ⚽

Fumarco & Rossi (2015) demonstrate wage differences for professional Italian Soccer players based on if they were born in the 1st quarter of the year (age cutoffs put them at an advantage in childhood) or the last quarter of the year (age cutoffs put them at a disadvantage in childhood).

Fumarco, L, G Rossi (2015), “Il titolare in squadra? Spesso è nato a gennaio”, Lavoce, available at
In American Football, success & career length is associated with position more than birthday, though disaggregated analyses of the Zodiac Effect by position have yet to be performed (Steingrover et al., 2016).

Football (MacDonald et al., 2009; Steingrover et al., 2016)

No Zodiac Effect for the NFL 🏈

Basketball (Daniel & Janssen, 1987; Cote et al., 2006; Steingrover et al., 2016; Brad Callas, 2017)

No Zodiac Effect for the NBA ‍🏀

Hockey (Baker & Logan, 2007)

Yups, in USA & Canada 🏒

Golf (Cote et al., 2006) ⛳

Golf is a game, not a sport. The game of golf has no Zodiac Effect.

Baseball (Greg Spira, 2008 — Slate) ⚾

“From 1950 to 2005, a baby born in the United States in August has had a 50% to 60% better chance of making the big leagues than a baby born in July. From August through the following July, there is a steady decline in the likelihood that a child born in the United States will become a major leaguer.

someone born on July 31, 1990, would almost certainly have been the youngest player on his youth team in 2001, his first year playing in the 11-and-12-year-olds league, whereas someone born on Aug. 1, 1989, by contrast, would have been of average age in 2001, his first year playing in the 11-and-12-year-olds division.

An analysis of the birth dates of players in baseball’s minor leagues between 1984 and 2000 finds similar patterns, with American-born players far more likely to have been born in August than July. The birth-month pattern among Latin American minor leaguers is very different — if anything, they’re more likely to be born toward the end of the year, in October, November, and December.

Chess (Breznik and Law, 2016) ♟

US Politics (Muller & Page, 2015)

Most elected to the United States House of Representatives were the oldest in their class when they were in school.

Solution = Bio-Banding

Sports like wrestling, boxing, martial arts, etc use bio-banding (e.g., heavyweight, lightweight, middleweight) to group competitors together in a way that removes discrepancies to promote balanced competition (Albuquerque et al., 2016; Delorme, 2014).


A Zodiacist is someone who discriminates against others based on their Zodiac sign.

My Hypothesis: Virgos Exhibit Poly-Calendar Outcomes

Because Virgos are ‘in-between’ the cutoff date, they display the greatest variability in terms of advantage/disadvantage of their birthday.

August Virgos will have the worst outcomes whereas September Virgos the best outcomes.

If Chad turns 5 on August 28th, and his friend 5 year old friend Magic Mike who joined the same class turns 6 on September 3rd… They were both 5 years old on September 1st but by it’s clear which one of them is most likely to make varsity when they tryout 10 years later in high school. Chad is going to have a more limited experience through school simply because he was born a late August Virgo instead of an early September Virgo like Mike.

Doyle & Bottomley (2018): Frequency vs Value

“Both clubs and countries selection policies appear to favor those born early in the competition year, but early-born players are no more skilled or talented than their later-born peers.

“children disadvantaged by birth date or physical maturity might have become equally skilled senior athletes if they were afforded equivalent developmental opportunities.”

But sadly they weren’t.”

Tales of the Traveling Gaussian (Doyle et al., 2017)

People enter school with particular qualities (Q). Q may be…

“a raw ability (e.g., running speed),
a nurtured talent (e.g., playing a violin),
or an attribute/characteristic (e.g., height).

As the group gets older, their development on Q increases (they run faster, are more proficient at violin, get taller), so that their Gaussian travels along the Q axis. In any given cohort (typically a school year or competition year) there will be a Gaussian centered at Q0 for the youngest, one at Q1 for the oldest, and one at each point in between.

Alternative Viewpoint: Parental Machiavellianism

Zhang & Xie (2015): “It is easier for parents of September–December-born children to manipulate the timing of their children’s school entry.”

Sidenotes Later lols

Parents’ In-Law Preference (Especially Daughters)

The United States is unique in the history if human civilizations as it has had marriages of choice since Columbus accidentally arrived here while looking for India (Furstenberg, 1966; Reiss, 1980). Importantly, other Western countries gradually worked themselves towards the romantic/choice marriages they have today, but the United States STARTED* that way.

Perilloux et al. (2008)

Parents place more importance on their daughter’s mate choice than their son’s. About two-thirds of daughters reported experiencing parental disapproval & receiving curfews compared to a third of sons.

Age of Remarriage

Men are more likely to remarry than women (Kuzel & Krishnan, 1973; Schoen et al., 1985; Chamie & Nsuly, 1981) & the sex difference in remarriage rates increases with age (Kuzel & Krishnan, 1973; Chamie & Nsuly, 1981; CDC Monthly Vital Statistics Report, 1995).
