You know that workout you keep putting off? The one where just thinking about it makes you want to scroll through your phone instead? Or that side project you swore you’d finish this year, but somehow it keeps slipping to next week, then next month?
The problem isn’t just about willpower or motivation. It turns out your brain is actively making these tasks seem harder than they actually are. And there’s a simple fix that researchers have been studying for years:
Do it with someone else.
When you tackle difficult goals with a friend or partner, something remarkable happens. The challenge genuinely feels less intimidating. Not because you’re dividing the work, but because your brain literally perceives the effort differently. Scientists call this the social catalyst effect, but I like to think of it as the Buddy Boost.
Let’s dig into why this works and how you can use it to finally make progress on those goals you’ve been avoiding.
Hills look steeper when you’re alone
In 2008, psychologist Dennis R. Proffitt ran a series of experiments that revealed something fascinating about human perception. He asked people to estimate the steepness of hills. Consistently, participants overestimated the angle by a huge margin. A 5-degree incline looked like 20 degrees. A 10-degree slope appeared to be 30 degrees.
When people were tired from running, carrying heavy backpacks, elderly, or out of shape, they judged the exact same hill as even steeper. The hill didn’t change. Their perception did.
Proffitt and his colleagues wanted to test whether social factors could work the same way. They had participants wear heavy backpacks and asked them to estimate the steepness of a 26-degree hill. Half the group stood alone at the base of the hill. The other half stood next to a friend.
The results were clear. People who had a friend beside them saw the hill as significantly less steep than those standing alone. In a follow-up study, even just imagining a supportive friend before making the judgment had a similar effect.
Think about what this means. Before you’ve taken a single step, before you’ve made any actual effort, your brain has already decided how hard something will be. And that initial assessment creates a psychological barrier that affects everything that comes after. Will you start? Will you keep going when it gets tough? Your perception of difficulty influences all of it.
Having someone with you changes that first domino. The task looks more manageable from the start, which makes you more likely to begin, and more likely to stick with it.
The power of just showing up together
One of the most interesting findings from group performance research is something called the Köhler effect. It describes what happens when people of different ability levels work together on a task that requires everyone’s contribution.
In the original 1920s experiments, German psychologist Otto Köhler had people hold weights at arm’s length for as long as possible. When individuals performed alone, stronger participants held out longer than weaker ones. No surprise there.
But when weaker and stronger participants were paired and told both had to keep going for the pair’s performance to count, something unexpected happened. The weaker member held the weight significantly longer than they had when working alone. They were motivated not to be the reason the team failed.
Later studies confirmed this effect in various contexts. When exercising with a partner who’s moderately better than you (not dramatically better, just a bit ahead), you’ll push yourself harder than you would solo.
This isn’t just about competition or not wanting to look bad. There’s a genuine psychological boost from feeling responsible to someone else and from the implicit challenge of keeping up with someone slightly ahead of you.
When accountability gets real
You’ve probably heard the advice to “tell someone your goals” to make yourself more accountable. It sounds reasonable, but it seldom work. You tell your friend you’re going to start going to the gym. They say “that’s great!” And then…nothing really changes.
Real accountability needs more structure than a casual mention. The research is pretty clear on what separates effective accountability from wishful thinking.
When performance is measured, performance improves; when performance is measured and reported, it improves exponentially. (Pearson’s Law)
One study on weight loss found that participants who had weekly accountability meetings lost an average of 17 pounds over six months. Those without structured accountability lost just 4 pounds. That’s not a small difference.
Different goals need different partners
Not every goal needs the same kind of partnership. Figuring out which structure fits your situation can be the difference between finally making progress and just adding another thing to feel guilty about.
Accountability partners work best for maintaining consistency on goals where the path is clear but motivation is shaky. Starting a daily writing habit, sticking to a workout routine, completing an online course. You know what to do, you just need help staying on track. The ideal accountability partner is also working on a similar goal and can match your commitment level. Research suggests avoiding close friends or family for this role because existing emotional dynamics can complicate things.
And sometimes the right partner is actually an app. For simple habit tracking, like drinking enough water or blocking distracting websites during work, technology provides consistent, judgment-free reminders. It can’t give you emotional support or nuanced feedback, but it’s reliable and always available.
The stuff that can go wrong
Not all partnerships work out. Sometimes having a partner makes things worse instead of better. Understanding the potential pitfalls helps you avoid them.
Poor communication creates friction. One study of workout partnerships found that the number one reason they failed was unspoken expectations about intensity, duration, and rest days.
Steps for building your buddy system
If you want to leverage the Buddy Boost for your own goals, here’s how to set yourself up for success.
Adapt as you go. What works in month one might not work in month three. If your check-in format feels stale, change it. If you’ve outgrown your current challenge level, adjust the goal. Successful partnerships evolve with you.
Lo esencial
When you have support, challenges literally look less intimidating. You show up more consistently because someone else is counting on you. And on the days when your own motivation fails, the structure of accountability keeps you moving forward anyway.
The science here is surprisingly robust. From perception studies showing that hills look less steep when a friend is present, to exercise research demonstrating massive performance gains with partners, to long-term studies on goal achievement showing dramatically higher success rates with accountability structures, the evidence points in one direction.
You don’t have to do hard things alone.
