Smartest Fan Bases in Sports

Key Insights

• Buffalo Bills fans score highest on the Gambling.com NFL intelligence index with a score of 8.405, driven by the largest share of post-secondary graduates at 31.5 % among all NFL fan bases
• New York Knicks fans rank fifth in the NBA intelligence index with 27.4 % post-secondary graduates and 55.5 % with upper-secondary education, both above league averages
• A 2025 multi-sport IQ study found that professional wrestling fans scored higher on average IQ tests than fans of the NFL, NBA, NHL, and most other major sports, which is genuinely the most surprising finding in recent sports research

The NFL Intelligence Index

Gambling.com commissioned a study on the smartest fans in the NFL using HypeAuditor data on the education level of each team's social media followers, combined with a meta-analysis that estimates IQ gains per level of education completed. The result is a ranked index that substitutes measurable data for the usual bar argument.

Buffalo Bills — 8.405

The Bills score highest in the league, driven by the largest share of post-secondary graduates at 31.5 % and more than half of fans with at least upper-secondary education at 54.3 %. Both figures are the highest in the NFL by this methodology. Bills fans being the smartest in the NFL also reframes Bills Mafia's reputation slightly, suggesting that the elaborate tailgate activities, the tables, and the general chaos might reflect a higher-than-average intelligence applied to extremely specific recreational choices.

Cleveland Browns — 8.400

Almost identical educational profile to the Bills, landing them just behind Buffalo in second place. The Browns fan base maintaining a top-two intelligence ranking through decades of results that have tested that intelligence significantly is either evidence that smart people can love anything or evidence that loyalty and intelligence aren't mutually exclusive the way sports culture sometimes implies.

Tampa Bay Buccaneers — 8.027

Third in the NFL index, with an educational profile that places them well above league average on both upper-secondary and post-secondary metrics.

Kansas City Chiefs — 8.010

Fourth in the index, with over 50 % of their fan base holding upper-secondary education and approximately 30 % with post-secondary degrees. The same fan base that ranks second in the delusional fan base survey also ranks fourth in the smartest fan base index, which suggests that intelligence and sports delusion are not incompatible conditions.

Green Bay Packers — 7.789

Fifth in the NFL, also with over 50 % upper-secondary education and approximately 30 % post-secondary graduates. The fan-owned franchise producing one of the more educated fan bases in the league is either a coincidence or a reflection of the specific kind of community investment that fan ownership creates.

The Interesting Footnote: Cowboys at Sixth

The same study places the Dallas Cowboys sixth in the NFL intelligence index. The fan base that 28 % of the NFL identified as the most delusional in the sport also ranks sixth-smartest by education-based metrics. This is either evidence that intelligence and delusion coexist comfortably or that being educated doesn't prevent you from believing it's your year every August for 30 years. Probably both.

The NBA Intelligence Index

Gambling.com applied the same methodology to the NBA, ranking fan bases by the educational distribution of their social media followers.

New York Knicks — Fifth in the NBA

The Knicks rank fifth in the NBA intelligence index with 27.4 % of fans holding post-secondary degrees, the second-highest rate in the league. 55.5 % of Knicks fans have upper-secondary education, and only 0.7 % have no formal education, both figures better than league averages. The fan base consistently described as the most loyal despite decades without a championship is also one of the more educated in the sport, which adds a layer to the question of whether staying committed to the Knicks is loyal or just evidence that smart people can absorb irrational amounts of sports disappointment.

The full NBA ranking isn't publicly detailed in the same way as the NFL study, but the methodology is identical: more education correlates to higher estimated IQ, producing a ranked list from highest to lowest by that measure.

The Result Nobody Expected

A 2025 multi-sport IQ comparison measured average IQ scores for fans across 12 different sports and produced a finding that generated significant content creator attention.

Professional Wrestling Fans — Highest Average IQ

Wrestling fans topped the chart across all 12 sports measured, scoring higher on average IQ tests than fans of the NFL, NBA, NHL, and every other sport in the study. Basketball and American football fans landed in the middle of the pack. The study doesn't mean every wrestling fan is a genius. It does mean that the long-standing cultural stereotype of wrestling fans as the least intellectually sophisticated sports audience is specifically wrong by this measurement.

The most useful application of this finding for a sports conversation is as a reminder that fan base stereotypes, including the intelligence-based ones, are frequently less accurate than the people applying them assume.

What the Data Actually Means

The education-based intelligence index is a proxy rather than a direct measurement. Higher education correlates with estimated IQ by the meta-analysis methodology the study uses, but it doesn't measure actual intelligence directly. It measures the educational profile of a fan base's social media followers, which introduces selection bias toward fans who are online and demographically skewed toward certain age groups and locations.

What it does provide is a more defensible framework than vibes-based arguments about which fan base is smartest. Bills fans having the highest post-secondary graduation rate among NFL social media followers is a fact. Whether that makes Bills fans the smartest NFL fan base is a question the data can inform but not fully answer.

The Buffalo Bills by the Gambling.com NFL intelligence index, with the highest post-secondary graduate share at 31.5 % and more than half of fans with upper-secondary education. The Cleveland Browns rank second with an almost identical profile.

Why do Bills fans score highest on the intelligence index?

The methodology uses the educational distribution of social media followers as a proxy for estimated IQ. Bills fans' social media audience has the highest proportion of post-secondary graduates in the NFL, which drives the top score.

Yes, by the Gambling.com education-based index. The same fan base that leads the delusional fan base survey also ranks sixth in the intelligence index. Intelligence and sports delusion are apparently compatible character traits, which anyone who has met a very smart person who still believes in their team against all evidence already knew.

What is the Knicks fan base's ranking in NBA intelligence?

Fifth overall in the NBA by the same education-based methodology, with 27.4 % post-secondary graduates and 55.5 % with upper-secondary education, both above league averages.

Is the wrestling fan IQ finding actually real?

The 2025 multi-sport IQ study measured average test scores across 12 sports and found wrestling fans at the top. It's a real study with a real result. Whether the methodology fully captures what we mean by intelligence in sports fandom context is worth questioning, but the finding itself is documented and specific enough to be worth taking seriously rather than dismissing as a punchline.

The smartest fan bases in sports are determined by actual data rather than which fan bases argue most convincingly that they're smart. Bills fans lead the NFL. Knicks fans are top five in the NBA. And wrestling fans beat everyone, which is the most useful reminder available that sports fan stereotypes are mostly wrong in the direction you'd expect them to be wrong.
