In 1978, Harvard researcher Ellen Langer ran a study at a photocopier that changed how behavioral scientists think about compliance. The finding was blunt: people don’t just follow reasons, they follow the word “because”, sometimes regardless of what comes after it. For freelancers writing cold emails, proposals, and follow-ups, this is one of the most immediately actionable findings in persuasion psychology.
The study design was simple. A confederate approached people waiting to use a photocopier and asked to cut the line. Three conditions:
- No reason: “Excuse me, I have 5 pages. May I use the Xerox machine?”, 60% complied.
- Real reason: “…because I’m in a rush?”, 94% complied.
- Fake reason: “…because I need to make some copies?”, 93% complied.
The fake reason adds zero information. Everyone in line was there to make copies. Yet compliance jumped 33 percentage points. The word “because,” Langer concluded, automatically triggers a reason-following script, a mental shortcut that says “a reason was given, therefore I should comply.”
Why “because” works: the automaticity principle
Robert Cialdini, in Influence, uses the Xerox study to illustrate what he calls “click, whirr” behavior, automatic responses triggered by specific stimuli. “Because” is that trigger for the reason-following script.
The brain is constantly managing cognitive load. Processing every request from first principles is expensive. So for low-to-moderate stakes situations, we rely on mental shortcuts: if a reason is given, the request is probably legitimate. “Because” is the word that signals “a reason is coming.” The brain pre-approves compliance as soon as it hears it.
At higher stakes, the quality of the reason matters more, but even then, stating any clear reason outperforms stating none. The trigger still activates; it just does less of the work at higher thresholds.
The critical insight isn’t that weak reasons work. It’s that stating no reason is the worst option. Even a thin reason beats silence. For freelancers who send asks without explanation, “Can we hop on a call?”, adding any honest “because” clause is an immediate, zero-cost improvement.
The “because” framework for cold outreach
Use this 3-part structure in any ask: Request + Because + Specific Reason.
The reason should be:
- Relevant to them, not to you
- Specific, not generic
- Honest, especially at high stakes
Here are five applications:
1. Cold email call request
Without “because”:
“I’d love to connect and learn more about your business.”
With “because”:
“I’d love to set up a 20-minute call because I noticed you just rebranded your pricing page and I have data on conversion patterns from three similar SaaS relaunches.”
The second version explains why now, why you, and why the call would be worth their time, all from one “because” clause.
2. Proposal follow-up
Without “because”:
“Just following up on the proposal I sent last week.”
With “because”:
“Following up on the proposal because two of my current clients just hit their Q2 targets and I’ll have a small window opening in mid-June, wanted to make sure you had first access before I commit that time elsewhere.”
The “because” turns a generic nudge into a logical, time-sensitive reason for responding now.
3. Referral request
Without “because”:
“Do you know anyone who might benefit from my services?”
With “because”:
“I’m asking because I’m specifically looking for fintech founders at the seed stage, if you have two or three in your network who are struggling with user acquisition copy, an introduction from you would carry real weight.”
Specificity in the “because” clause makes the ask more actionable and signals you’ve done the targeting work.
4. Rate increase communication
Without “because”:
“My rates are going up in July.”
With “because”:
“My rates are increasing in July because I’ve added a post-delivery analytics review to every engagement and I’m limiting my active client roster to four projects at a time to protect quality.”
The “because” converts a policy announcement into a reasoned value update.
5. Proposal pricing justification
Without “because”:
“This project is $9,500.”
With “because”:
“This project is priced at $9,500 because it includes a full content audit, eight long-form pieces, two rounds of revision on each, and a 90-day performance tracking report, total is approximately 80 hours of focused work.”
In pricing conversations, the “because” clause serves a second function: it makes price reduction psychologically harder. If the client knows your price maps to specific deliverables, asking for a discount means explicitly cutting something. That’s a much harder conversation than simply negotiating an abstract number down.
When “because” backfires
The effect weakens when:
- The reason is visibly false. At high stakes, prospects will evaluate the reason you give. A thin or implausible reason is worse than a genuine one.
- You use it too often in one communication. If every sentence contains “because,” the word loses its trigger effect, it becomes noise.
- The reason is self-serving without acknowledging them. “Because I need more clients” is technically a reason, but it creates zero value for the reader.
The rule: use real reasons, keep them prospect-centered, and use “because” deliberately, not as filler.
The “because” audit: reviewing your outreach
Take your last five cold emails or follow-ups. Mark every ask you made. For each ask, answer: did you include “because + specific reason”?
Most freelancers find 40–60% of their asks are reason-free. Those are immediate opportunities. Add a genuine “because” clause to each one and resend the template.
Track response rates over the next 30 sends against your previous baseline. The lift is rarely zero.
The integrity version of this technique
Cialdini’s concern with the Xerox finding wasn’t that it enables manipulation, weak reasons work at low stakes, but thin justifications for high-stakes decisions erode trust when examined. The ethical application is straightforward:
Use “because” to make your genuine reasoning visible. You usually have real reasons for every ask you make. The problem is that those reasons live in your head and never make it into the email. “Because” is the bridge that puts your thinking on paper, where the prospect can evaluate it.
That’s not manipulation. That’s legibility.
