Thanking your team isn't a soft skill. It's an instruction that travels.

You closed a hard quarter last week. Somewhere in there you probably fired off a two-line Slack message to your VP of ops — nice work getting that account back on track, I know it wasn't easy — and moved on to the next fire. You didn't think about it again. You had no reason to. It felt like a small, private courtesy between two people.

A new study says it wasn't private, and it wasn't small.

The paper is "Grateful Leaders and Attentive Followers: How Grateful Attention Transmits the Cascade of Gratitude Expressions to Strengthen Coworker Relationships," by Lauren R. Locklear (Texas Tech University), Meghan E. Kane (Temple University), and Mark G. Ehrhart (University of Central Florida), in press at the Journal of Applied Psychology. I read the authors' full manuscript, not a summary of it.

It's three separate studies, and the design matters here. The first surveyed 233 real supervisor-subordinate pairs across a mix of industries, with the two people in each pair answering at different points two weeks apart, so one person's report of gratitude wasn't just echoing the other's report of the same conversation. The second followed 204 administrative employees at two public universities through three separate weekly surveys, tracking the same people over time rather than asking everyone the same question once. The third was a controlled experiment — 162 working adults recruited through Prolific, split into conditions, reading a scripted email exchange and responding as if they were the supervisor or subordinate in it. All of it is self-reported. None of it involves fly-on-the-wall observation of an actual workplace. That's a real limit, and the authors say so themselves.

Here's what they were testing: when a leader expresses gratitude to a direct report, does that gratitude keep moving — to the next level down, and the level below that — and if so, how? They ruled out the two obvious explanations. It isn't that people copy their leader's behavior on autopilot. It isn't that a good mood is simply contagious. What predicted the spread, consistently across all three studies, was something narrower: seeing a leader express gratitude made people pay more attention to the good things already happening around them at work. The authors call this grateful attention — noticing benefits you'd otherwise have let pass — and it's what triggered the next person to say thanks to someone else, which in turn tightened that person's relationship with their own coworkers.

"...gratitude is not simply a behavior to be mimicked or an emotion to be caught, but it is a signal that shifts employee attention, underscoring the powerful role of leader gratitude in cultivating a more grateful workplace." Locklear, Kane & Ehrhart, "Grateful Leaders and Attentive Followers," Journal of Applied Psychology, in press — read in the authors' posted manuscript

There's an honest wrinkle worth keeping. In the lab experiment, the gratitude thinned out as it traveled — a manager's three expressions of thanks became fewer than two by the time they reached the simulated subordinate. In the two real-workplace studies, it didn't thin out that way; people at every level reported expressing gratitude at similar rates. The authors flag this themselves and don't resolve it — a single scripted email may just behave differently than a week of real interactions. I'm not going to resolve it for them either. It's a reason to read the finding as "gratitude cascades" and not "gratitude cascades undiminished, guaranteed."

Here is why this lands differently for you than for anyone else in the building. A department head who forgets to say thanks has a bad week with their team. You, forgetting to say thanks, are setting the attentional baseline for people you will never personally manage and may never meet — the hire in year three, the shift lead at the location you visit twice a year. You are not just failing to reward one person. Per this research, you are failing to hand down the cue that tells everyone downstream what's worth noticing at all.

The part the research doesn't say, but that I'll say plainly: if gratitude is a cue about what to pay attention to, then so is everything else you say out loud in front of your team — including the things you complain about, the wins you skip past, and the corners you visibly cut. The study only measured gratitude. I think the same mechanism runs in both directions, and I don't have a study to back that half of the claim. Treat it as my inference, not their finding.

Here's the one thing to do this week. Pick one specific, recent piece of good work from someone two levels below you — not your usual favorite, not a vague "great job team" — and thank the person who actually did it, by name, for the specific thing, where at least one other person can see or hear it happen. Not a private DM. The study's whole finding is that gratitude only cascades when someone downstream gets to witness it.

If you want a clearer picture of what you, specifically, model for the people below you under normal pressure — not just gratitude, but the whole pattern of what you reward and what you let pass — that's what the Leadership Profile is built to surface. It's $47, and it's at /wiring-map.
