Simplicity Over Value: Why Casual Bettors Accept Worse Odds

To get a little more, you’d have to leave the app, go to another sportsbook, and do some math on the odds. That takes time and effort. And it's definitely expensive.

Instead, you tap the button for the parlay. That’s easier and more fun, even if it has a worse expected value. The simplicity is worth more than a small edge.

The Math Everyone Ignores

If only bettors had to think about odds, they'd go with straight bets. A $50 moneyline at -110 pays about $95 if it wins, and if three separate $50 straight bets win, all three generate about $155 in total profit. On the other hand, a three-leg parlay ^[1] with the same three picks pays $595 from one $50 bet if all three win. And this is 3.8 times more!

Usually, the payout increases, but the odds of winning decline, so the payouts increase. Still, parlays represented 70% of online sportsbook revenue in Louisiana in fiscal 2024 ^[2], and it’s not by accident.

Why the Simple Bet Wins

Decision fatigue is when your brain gets tired from making too many choices, so you take the easy route ^[3]. In sports betting, opening the app, selecting your team, and clicking “GO” places a moneyline bet. A parlay builder is as simple, except it’s dressed up. It sits at the top, displays the payout in real time, and just asks for a tap.

The real challenge is finding value within each app. You have to switch apps, look at the lines, and do quick math on implied probability. That takes more brain power. When people are tired, they go with the first button that shows in the app. And clearly, default is the easiest bet.

The Reward Psychology

There’s another layer: Control and big wins. The excitement of winning three $50 bets isn’t the same as winning a $595 parlay payout, even if the profit is identical. A parlay win feels like a jackpot, offering the same reward centers as a lottery ticket—that “I beat the odds” sentiment that winning individual bets don’t provide.

Moneylines ^[4] are boring and consistent. Parlay is a story; it’s the kind of bet that gets posted on Twitter. Moneyline? That’s expected.

So even though bettors may understand the math intellectually, the reward of winning a parlay is more rewarding than the rationale of placing more straight bets.

Where the Logic Breaks

And there is also a reason why licensed sportsbooks talk about parlay winners even after they have lost a lot of money ^[5]. Parlays give sportsbooks a bigger advantage than regular bets. They don't push parlays because they are better for the player, but because they make more money.

Parlays have a greater margin of profit. The house usually wins more frequently. The player gets less value.

But it's difficult for most casual bettors to find better odds. They don't want to switch between apps, check different NBA and MLS lines across sportsbooks, and do math to save $5 or $10 on a $100 bet. They are willing to go through the hassle just for the sake of simplicity.
