Debunking the Hot Hand: A Data-Driven Look at Basketball Shooting Streaks

Have you ever heard basketball commentators talk about a player being “on fire” or having a “hot hand”? It’s one of basketball’s most enduring beliefs — the idea that making a shot increases your chances of making the next one. But is it real? Let’s dive into some fascinating data analysis that might surprise you.

The Kobe Bryant Case Study

We analyzed Kobe Bryant’s performance during the 2009 NBA Finals, where he led the Lakers to victory and earned MVP honors. Many fans swore he had the hot hand during this series. With 133 shots to examine, it was the perfect dataset to test this theory.

What We Were Looking For

The hot hand theory suggests that making a shot increases the probability of making the next one. If true, we should see:
- Longer streaks of successful shots than random chance would predict
- Patterns that differ from what we’d expect from independent events
- Clear evidence of “momentum” in shooting sequences

The Analysis: What We Actually Found

We tracked “streak lengths” — the number of consecutive shots made before a miss. Then we compared Kobe’s actual performance to a computer simulation of a shooter with the same 45% accuracy but whose shots were completely independent (no hot hand effect).

The results were striking:
- Kobe’s most common pattern was actually missing shots (streak length 0)
- His distribution of streak lengths almost perfectly matched our simulation
- His longest streak was 4 shots — exactly what random chance would predict

The Surprising Conclusion

The data suggests that even for one of basketball’s greatest players, during one of his most celebrated performances, there’s little evidence of a hot hand effect. Each shot appears to be independent of the ones before it — just like flipping a coin.

Why This Matters

This isn’t just about basketball. It’s about how humans perceive patterns in random events. We’re naturally wired to see streaks as meaningful, even when they’re just normal statistical variation. This same tendency affects how we view everything from stock market trends to gambling.

The Takeaway

Next time you hear about a player being “hot,” remember: what looks like a hot hand might just be the normal ebb and flow of probability. It doesn’t make those amazing shooting performances any less impressive — it just helps us understand them better.

Google Search can't be trusted anymore

I Can No Longer Trust Google's Search Results, and It's Honestly Scaring Me Because of Google's advertising-driven model, I no longer trust its search results. We all know the first page of results isn't necessarily what’s most relevant—it’s often what someone paid Google to show us. I find myself increasingly wary of using Google, preferring Bing—not because it's the best, but because it gives me more straightforward, relevant results. I remember searching for the Astoria Hotel in Dubai a while back. I typed the hotel's name and address into Google, expecting to find its official website. But the entire first and second pages were cluttered with third-party booking sites like Booking.com, Hotels.com, and similar services. It took persistent digging to find the actual hotel website, even though I had been specific with my search query. Out of frustration, I tried Bing with the exact same search. The hotel's official website appeared as the second result—simp...

It’s a playbook for modern organizations navigating the stormy seas of data governance, compliance, and innovation. This article breaks down what TD did right, where they stumbled, and what every organization (yes, even yours) can learn from their experience. The Backdrop: A Data Giant Wi...

In The Shadow of a Giant: How GOP Candidates Strategically Positioned Themselves Around Trump in the 2024 Primary.

Image
When it comes to presidential primaries, much of the focus tends to be on what candidates say — but what about where they go, and when? Political campaigns have always been a choreographed dance, with candidates carefully plotting where and when to make appearances. But what happens when one contestant dominates the dance floor? The 2024 Republican primary featured former President Donald Trump as the overwhelming frontrunner, creating a unique dynamic where other candidates had to make strategic decisions: should they follow in Trump’s footsteps, or deliberately chart their own path? This article presents a data-driven analysis of how Republican presidential hopefuls positioned themselves relative to Trump throughout the primary campaign. Using a novel “shadow zone” approach, we examined 1,741 campaign events to reveal previously unseen patterns in campaign strategy and t answer a subtle but important question: Did GOP candidates follow Trump’s campaign trail to tap into his media buz...
