Commitment bias
Why people stick to past decisions to protect their self-image and how to use commitment bias to increase customer loyalty and sales.
In this issue
Hey 👋 The Crew here.
Ever stuck to a marketing strategy that was obviously failing just because you didn’t want to appear wrong among your colleagues or bosses?
If you did, you might’ve allowed your commitment bias to get the best of you.
And that’s something we’ll explore deeper in this issue…

Scalable newsletter growth for $1 CPL with this secret tool

Do you want “stalker-level” subscribers who crave quality content in your industry?
TrafficGrid uses over 30 intent signals to build hyper-targeted audiences to advertise your newsletter. These US-based subscribers open at a 40%-60% rate, and are only around $1 CPL.
And those highly engaged readers turn into clickers.
Just last month, a client generated 26,654 new subscribers and saw 12.5% of them turn into clickers in under 30 days.
If you already have a list of 5,000 subscribers or more, you could qualify for a free campaign from TrafficGrid to test these subscribers out in your own newsletter and see the results first hand.
Here’s a story for you: A hiring manager recruits a good candidate to fill in a high-level position.
The manager is full of praise. They publicly applaud the candidate’s skills and potential.
… But then the new recruit underperforms.
After a while, it’s clear the new hire is a poor fit.
And yet, the hiring manager refuses to replace them because they feel it will undermine their own credibility and commitment they made. So they stick to their guns, despite the obvious.
This is a typical case of Commitment bias—also known as escalation of commitment. It’s our tendency to stick to past statements or behaviors, regardless of the outcome.
… Especially when we expressed them publicly.
Sounds like Sunk-cost fallacy, right? It is… kind of.
But in this case, it goes deeper than wasting resources—you don’t want to waste your own self-image.
A 1976 report by Barry M. Staw was the first to confirm this bias. He had 240 students participate in a role-playing investing exercise.
The outcome? Those who were personally responsible for doling out negative consequences stayed true to their initial decisions to do so.
And just like sunk cost fallacy, commitment bias can be a powerful selling tool…
Three ways to leverage Commitment bias
Get them to start with a small commitment
Ever heard of the foot-in-the door technique?
It’s when you start with a low-stakes, easy request. If the other person complies, you follow up with a bigger one.
The idea is that people who commit to the initial request are more likely to agree to the subsequent, bigger request.
Why? To remain consistent with their earlier behavior.
This is one of the best in-action examples of commitment bias. And brands do it all the time.
Most SaaS subscriptions offer a free trial, which is cool. But they also ask you to commit your credit card information. Which is not that cool.

Brands may tell you they do it to avoid any abuse. And that’s true, partially.
But beyond that, this is a natural way to get you to commit—because later on it will be easier for you to pay the subscription.
Tie your product to a cause
Like we said, people often stick to commitments—especially if they align with their own self-image.
And there’s a simple way you can take advantage of that.
Frame the purchase decision as aligning with your customers’ identity by tying it to a relevant cause.
Your potential customers are already committed to certain values. When you reflect those values in your branding, you are appealing to their commitment bias.
Say you’re someone who cares deeply about marine life. And you come across an apparel brand that feels the same way:

You will probably spend to support that brand.
And you’ll also probably keep supporting them once you’ve committed.
In a nutshell, leverage storytelling to touch upon the values that reflect those of your customers. It works.
Reward consistency
Your customers want to maintain a positive self-image by staying true to their past decisions.
… And you can help them.
Make sure you reward your customers for regular engagement, loyalty, and longevity, because this will reinforce their sense of loyalty to your brand.
Some examples of this include:
- Loyalty programs that reward frequent actions like repeat purchases.
- Progress trackers and visual tools for achieving rewards and completing tasks.
- Longevity rewards like premium prices for long-term subscribers.
Booking leverages commitment bias with its “Genius” program, which encourages you to book more in order to unlock extra perks:

Start doing this, and you’ll probably prefer Booking to similar services—and might even hold it in a more positive regard.
All of this creates a positive feedback loop. By rewarding commitment, you’re making your customers commit even more.
A “commit-ception,” if you like.

ADVERTISING:Last year, marketers held their wallets tight and their budgets reasonable. But this year, that might change. Various data shows that marketing leaders are feeling more optimistic about the economy this year and might be ready to splash the cash. Check the report.
TIKTOK: …It seems like this Sunday might be TikTok’s last day in the US and—If banned—the platform plans to shut down its features. However, the US Senate can pass the bill which gives ByteDance more time to sell the app and delay this. Let’s wait.
AI MARKETING: AI search is becoming a decent traffic source, apparently. One brand saw a 400% and 436% increase in sales after their article on safer tampon options started appearing as a source on ChatGPT and Gemini. Is this the first AI SEO case study?
