Why the bias matters more than you think
Betting on the favourite feels safe, but it’s a mirage. The longshot bias is a silent thief, stealing potential profit from the unwary.
The anatomy of the bias
Bookmakers, in a bid to balance books, nudge odds toward the favourite. That creates a systematic overvaluation — think of it as a rubber band stretched too far, ready to snap.
How the market feeds the illusion
By the way, casual punters chase the hype, flooding the market with cheap money on the hot name. The result? Odds shrink, and the true value disappears.
Real-world impact on bankrolls
Look: a ten-pound stake on a 2/1 favourite returns £30, but a similar stake on a 20/1 longshot can explode to £210. The bias keeps you stuck in the modest lane.
What the data says
Studies show favourites win about 35% of the time, yet they’re priced as if they win 50% of the time. Longshots, conversely, are underpriced. The math is simple — bet the undervalued.
Psychology of the crowd
And here is why the bias persists: herd mentality. When the crowd screams “sure thing,” you hear a whisper of “overpriced.” Ignoring the roar can be lucrative.
Practical steps to exploit the bias
First, filter out races where the favourite’s odds are under 3.0. Second, compare the implied probability to historical win rates. Third, allocate a modest percentage of your bankroll to the most egregiously mispriced longshots.

Finally, remember: the bias isn’t a myth, it’s a market flaw. Spot it, exploit it, and let the odds work for you. Stop chasing the favourite, start hunting the longshot.
