There’s a psychology term recruiters love to misquote: the Zeigarnik Effect. Pop-science version says unfinished tasks haunt your memory more than finished ones. Comforting story. Mostly wrong, and not in a “well actually” pedantic way, in a “someone finally ran the numbers” way.
Ghibellini and Meier at the University of Bern pulled together decades of interruption research into a proper meta-analysis and found no overall memory advantage for unfinished tasks, though they did confirm a general tendency for people to go back and resume them. The pooled effect for the memory claim was so small it’s barely worth reporting. What replicated was the urge to finish, not the memory of having started. Which is a genuinely different mechanism, and recruiters have spent decades leaning on the wrong one. ResearchGate
Here’s why that distinction actually matters rather than being a fun trivia fact for your next dinner party. If the mechanism were “candidates remember unfinished processes vividly,” you could theoretically get away with silence, because the impression would stick regardless. But if the mechanism is “people feel a pull to resume things, conditional on it still seeming worth resuming,” then silence doesn’t preserve your position. It erodes it. Every day without contact is a day the “still worth resuming” calculation gets a little worse for you.
There’s a second, less quoted piece of research that I think is more useful than the Zeigarnik headline anyway. A 2026 meta-analysis in Anxiety, Stress & Coping looked specifically at unfinished work tasks and off-job rumination, pooling seventeen between-person studies covering roughly 2,470 people and fourteen within-person studies covering over 12,000 observations. The conclusion, stripped of the academic hedging: open loops don’t just sit there quietly, they actively colonise your evening. Now apply that to a candidate. They’re not filing your vacancy away in a folder marked “pending.” They’re carrying it into dinner with their partner. Wikiwand
So what does the data actually say about why candidates leave the process, rather than why we assume they do?
There’s a dissertation out of Clemson that tracked roughly 25,000 applicants to a manufacturing company across four stages of selection, and the strongest predictors of withdrawal weren’t demographic or administrative. They were perceptions of person-job fit, person-organisation fit, and offer expectancy. In plain English: candidates don’t leave because the process is slow. They leave when the process stops giving them a reason to believe an offer is actually coming. ResearchGate
A separate study of 5,346 applicants to a European military organisation found something that should be printed on every recruiter’s monitor. The amount of information candidates had about the selection process, and their confidence navigating it, both reduced withdrawal, while the time elapsed since application and the presence of alternative offers both increased it. Two levers pulling in opposite directions. One of them, information, is entirely within your control. The other, competing offers, isn’t, but it gets worse the longer you let the first one sit unaddressed. You can’t stop a candidate getting another offer. You can absolutely stop them feeling like yours has gone quiet in the meantime. ResearchGate
Now, ghosting. This is where it gets more interesting than the tidy “silence causes ghosting” narrative I gave you last time, because the full research picture is messier and (as always) I’d rather give you the messy version…
Yes, ghosting correlates with a broken psychological contract. A 2024 study in the Journal of Occupational and Organisational Psychology frames it exactly that way, describing candidate ghosting as a violation of the fair expectation that both parties in a hiring process will actually respond to each other. But the same study also found individual dispositional traits, including low self-control and fear of missing out, predict who’s more likely to ghost in the first place. So it’s not purely situational. Some of it is just who the person is. Which, if I’m being properly honest with you rather than just building you a tidy narrative, means “fix your communication and ghosting disappears” is an overclaim. Fix your communication and you shift the odds. You don’t rewrite anyone’s personality. Omni RMS
Still, the feedback side of this is where the evidence gets genuinely actionable. A 2023 study gave 554 unemployed job seekers a mock application process and split them into three groups: personal feedback, impersonal feedback, and straight-up silence, then measured what happened to their psychological needs satisfaction. Ghosted candidates fared worst. Not “slightly worse.” Worst. Even bad news, delivered as news, beat no news at all. ResearchGate
And the scale of this problem is not small. A 2026 industry survey found 53% of candidates report having been ghosted by an employer, and a separate UK study found 94% of candidates dropped mid-interview-process by ghosting said it left them with negative feelings about the employer. Meanwhile, on the flip side, Indeed’s data shows 28% of applicants admit to ghosting a recruiter, versus 76% of recruiters who say they’ve been ghosted by a candidate, which tells you something uncomfortable about whose perception of “ghosting” is more expansive. Recruiters feel ghosted more often than candidates admit to doing it. Make of that what you will. I have a theory and it isn’t flattering to either side. X0PA AI + 2
So where does that leave the actual practice?
Close loops the second you’re able to, not when it’s convenient. The Clemson data says fit perception and offer expectancy drive withdrawal, so every update is a chance to either reinforce or quietly erode those.
Report the next milestone, not the current stall. The military applicant study is basically a controlled experiment proving that information and self-efficacy reduce withdrawal. “Still waiting” gives someone neither.
Don’t confuse activity with progress. Sometimes the honest update is “nothing’s changed, here’s exactly why,” and the work-rumination data suggests that’s still worth sending, because the loop is occupying their headspace whether you address it or not.
Post-interview is peak investment, and also peak risk, because that’s precisely the point where “still worth waiting for” starts running its silent calculation against you.
Track your open loops as a workload metric, not just your vacancies. Candidate awaiting feedback, client awaiting shortlist, offer awaiting sign-off. That’s the actual pressure map of a desk.
And don’t manufacture suspense to manage any of this. The evidence doesn’t say “keep people psychologically hooked.” It says “give them information and a sense of control.” Those are not the same instruction, and confusing them is how you end up in the 53%.
The lesson was never “move faster.” The data is fairly consistent that it’s “be predictable, be informative, and don’t let the silence do the talking for you.” The entire gap between a candidate who sticks around and one who ghosts you often comes down to whether they know what happens next, and whether they still believe you.
