Research reveals that video call glitches, which occur in 30-50% of calls due to internet issues, computer limitations, or software problems, significantly undermine trust and positive perceptions of communication partners. Studies show that glitches reduce trust in speakers by 16%, decrease interest in in-person meetings, and can lower parole grant rates by 12 percentage points. The uncanny nature of glitches—freezes, stuttering, and delayed speech—breaks the illusion of real personal interaction, making people feel unsettled. Interestingly, making jokes about glitches may help offset this negative effect, while acknowledging glitches or warning in advance does not help. This has significant implications for telehealth, virtual courtrooms, and job interviews, potentially widening societal gaps based on internet access quality.

Zoom Calls Are So Much Worse For Us Than You ThinkAdded:
Ever since the pandemic, a ton of us are spending long chunks of our day on Zoom.
Or Google Meet, or Teams, or – Skype??
Every time I have to say “oh sorry, I think your mic cut out there”, I feel a little bit of my soul escape from my belly button.
Though as annoying as it is, video calls do keep me from having to wear pants and commute to the office, and it doesn’t really affect my work all that much.
So for me it’s a worthwhile trade.
I’m not alone in that. 70% of people say that glitches in Zoom calls don’t affect how they view the person they’re interacting with.
Except it turns out, that’s not actually true.
A 2025 study suggests that these seemingly insignificant blips can have life-altering impacts.
[intro music] Glitches are whenever there’s a temporary disruption in the audio or video of a video call.
This could be because your internet can’t meet the high demands required for video streaming.
Or because your computer is spending too much of its memory running other programs.
Or because of outdated software.
Or, sometimes, because of platform issues and outages.
Whatever the reason, the result is your video and audio de-syncing, freezing, dropped frames or phrases, or even straight-up crashing.
It always manages to freeze and crash on the most unflattering face you’ve ever made, too.
One small survey found that folks experience glitches in about 30-50% of their video calls.
Since they’re so frequent and typically out of our control, it’s no wonder we feel like we don’t hold it against anyone.
Just breathe in, breathe out, and let those glitches go.
But as with so many things in psychology, how we feel and how we behave don’t necessarily align.
In 2025, researchers in the US published a study that looked at the effects of video call glitches on our perception of conversation partners.
Basically, in various situations, do we judge people differently when glitches occur?
So, for example, when participants watched an online webinar by a health coach talking about the benefits of using sunscreen, they understood the point the coach was making, regardless of glitches.
But they trusted the speaker less if the video froze.
And when the glitches happened, 16% fewer participants indicated that they would be interested in meeting the health coach in person and working with them one-on-one.
That’s super important to consider when we’re living in the era of telehealth.
There were similar results for other domains with equally serious implications for our lives.
One experiment showed that in the context of a job interview, glitches could lower interest in hiring or supporting that candidate by over half a point on a seven point scale.
That’s an 8% drop, nearly a whole letter grade!
So if your call glitches during the interview, that can affect the likelihood you get hired.
Of course, this was all measured during controlled experiments, and the researchers wanted to know if we actually see it play out in real life.
So they looked at four months of court transcripts from virtual parole hearings in Kentucky.
That was 472 hearings.
They scoured the transcripts for indications that the video had glitched.
Phrases like “we lost you for a minute” or “I think you glitched”.
Around 33% of calls had these glitches, which is about the same amount that people had self-reported in that first survey we mentioned!
Anyway, they found that 60% of people were granted parole if their video hearing was smooth, whereas only 48% were granted parole if there had been a glitch.
That’s twelve points less likely to be granted parole, just because your internet was bad.
The researchers tested whether this result might be due to glitches making it harder to understand what your communication partner is talking about, or because disruptions are frustrating, or even because people blame the person experiencing the glitch.
But none of that seemed to entirely account for what’s going on.
Before we tell you what they think is going on with glitches, we’ve gotta run a quick ad.

Instead of glitches merely being frustrating, the research team suggests that glitches are just downright uncanny.
Freezes and stuttering movements and delayed speech don’t occur in real life conversation.
So they make something seem just a little bit off and leave us feeling unsettled and kind of creeped out.
Essentially, glitches break the illusion that we’re having a real, personal interaction.
That isn’t great for how much we trust our communication partner, or even for how much we just like them.
This effect panned out in the research team’s study, with people reporting a greater sense of uncanniness when there are glitches in a conversation.
Study participants found certain glitches more uncanny than others.
“Sustained freezes” and “video distortions” like pixelation were ranked as least disturbing.
Whereas echo, “fleeting freezes”, and “sustained video loss” were given the highest uncanniness scores.
The more uncanny the glitch, the more it hurt the glitchy job candidate.
But remember earlier that I said 70% of people reported that glitches don’t impact how they view the person they’re talking with.
That might be because they know glitches shouldn’t impact their judgments, so they responded to the survey in a way that makes them look, or feel, better.
But it’s also possible that this is all subconscious, and we don’t even realize that glitches are affecting us.
So what’s a virtual girl to do?
The researchers tested some potential solutions, though the results weren’t super encouraging.
Warning people in advance that glitches might occur didn’t make much of a difference at all.
Acknowledging a glitch after it happened, saying something like “sorry for the glitch” or “I think I glitched there”, actually made things worse.
One avenue that did show promise is making a joke about the glitch, which the researchers think offsets the uncanniness factor by explicitly reminding your conversation partner that the glitch is harmless.
It’s worth continuing to study how to lessen this effect, and also to keep it in mind as policies, technology, and video chat scenarios evolve.
For example, some states have permanently moved parole hearings to virtual courtrooms because it’s cheaper and more secure than transporting incarcerated people to a physical courtroom.
Those are real advantages, but it also means that people in jails and prisons with poorer internet connections and fewer resources are less likely to get parole than people in facilities with good wifi.
And telehealth has been touted as a solution for people in low-income and rural areas who may be far from doctors’ offices or not able to get away from work to make the trip.
But the people who turn to telehealth because they can’t easily access doctors’ offices are the same people who have less reliable internet connections.
Telehealth may improve access to treatment, but it might also cause folks to trust their providers less.
Or their providers might perceive them as less reliable patients.
As with basically every technology ever, video conferencing has been great for expanding access to previously inaccessible resources, and for making many people’s lives easier.
But it has also potentially widened gaps in our society that already existed.
Moving forward, we need to ensure our technology glitches aren’t leaving anyone lagging behind.
