Your audience doesn’t switch off at minute ten. Audience attention actually starts to wander within 30 seconds, comes back, drifts again, and keeps doing that for the whole session. Design your event sessions for that rhythm and you can hold a room far longer than the old rule says you can.
That’s the headline from chapter one of Live Group’s The Audience Report 2026. If you’re building agendas for 2027 right now, and most event teams are, it’s worth five minutes of your time before the next draft goes to the client.

The Audience Report 2026
Where did the ten-minute attention span come from?
It came from a study that measured note-taking. Bradbury’s 2016 review in Advances in Physiology Education traced the claim back to its source and found that the most-cited study tracked how much students wrote down. In the same study they found that note-taking isn’t a reliable sign of attention at all.
So the rule stands on wobbly legs, yet event organisers are still designing entire conference programmes around it, and it’s started to shape a pricey habit in events: short, glossy, single-voice segments stacked one after another. If the rule doesn’t hold up, that format may be solving a problem nobody has while creating an entirely new one.
The ten-minute rule is a myth with a long shelf life, and plenty of agendas are still built around it.
So how long do audiences really pay attention?
Not long in one stretch, but they keep coming back. In a 2010 study, Bunce, Flens and Neiles asked students to report lapses in real time with clickers. Some lapses came within 30 seconds of the start. Another cluster landed at about four and a half minutes. After that, attention rose and fell in cycles that got shorter as the session went on.
The detail that matters most is how long each lapse lasted. Most were a minute or less. Picture a car radio in a tunnel: it cuts out, crackles, then it’s back. Your typical delegate checks out fifty times for forty seconds. Very few vanish for half an hour.
That sounds worse than the ten-minute rule. But event planners will be pleased to know it’s actually better news. If a delegate’s mind wanders for 40 seconds, they just need an excuse to be pulled back in.
| The old rule about attention | What the research shows | What to do with your agenda |
| Attention holds for 10 minutes, then drops | Lapses start within 30 seconds and recur in cycles | Plan regular moments that pull attention back |
| Disengagement is one big drop-off | Most lapses last under a minute | Frequent short resets matter more than session length |
| Shorter sessions fix the problem | A format change resets attention, even after it ends | Change the format, not only the running time |
Attention will inevitably flicker. Your job is to make sure it always has somewhere to land.
What actually brings attention back?
A change of format brings it back. In the same study, students lapsed far less during demonstrations, group work and clicker questions than during straight lecturing. This benefit carried over, with attention staying higher in the lecture segment that came straight after the interactive moment.
For example, poll at minute 12 of a 40-minute session does more than offer a short respite – it lifts some of minutes 13 to 40 as well. That makes the poll on Slido or Mentimeter part of the structure, because of how it encourages interaction for everything after the fact.
Does swapping speakers count as a format change?
Not quite – one voice handing over to another keeps the audience in the same place. The reset comes when people have to do something: vote, discuss, interact.
Format changes earn their place twice, once while they run and again in the minutes after.
Should you ban phones from the room?
The temptation is to remove all potential sources of distraction, but your audience deserves to be treated with trust. The onus is on the speaker to make the session worth ignoring phones for.
Rather than working against the phones, give them a job. Kuznekoff, Munz and Titsworth (2015) ran 145 students through a 12-minute video lecture under different phone conditions. Students who texted about unrelated things scored roughly a letter grade lower. Students who texted about the lecture scored close to the group with phones put away.
Clearly, the problem doesn’t lie with the device. What’s on the screen decides whether a delegate is with you or thinking about something else. If you don’t give the second screen a role, through live Q&A, polling or a session app like Cvent or Bizzabo, the delegate’s feed or employer will happily fill that gap for you.
The phone in your delegate’s hand can work for your session or against it, and you get to choose which.
Is the post-lunch slot really that bad?
Yes, though the evidence here is softer, and the report says so plainly. The best-known effect is the post-lunch dip, a fall in alertness between roughly 14:00 and 16:00. It’s partly down to the body clock rather than the food, so a lighter lunch won’t save you. Researchers have even tested bright light as a fix, with some success.
Anyone who’s sat through a 2.30pm keynote after a hotel buffet knows the feeling of fighting through heavy eyelids. The answer is to put your most interactive session in that window. Workshops, structured discussion and polling-heavy formats belong there. A text-heavy slide show does not.
Treat early afternoon as your toughest slot and staff it with your liveliest format.
How do you design a session around the 40-second lapse?
Plan for returns, not running time. Here’s a simple way to map a 40-minute session:
| Minute | What happens | Why it helps |
| 0–2 | Open with a question or quick poll | Catches the early 30-second lapse |
| 10–12 | Live poll or show of hands | Resets attention for the middle stretch |
| 20–24 | Pair discussion or a short case example | Moves people from listening to doing |
| 30–32 | Audience questions via an app | Gives the quieter half of the room a voice |
| 36–40 | Everyone writes down one action | Turns attention into a plan |
None of this needs a bigger budget. It needs a different question at the planning stage: how many times in this session does the audience get a reason to come back?
Count your returns, and the minutes start to look after themselves.
Where does an events agency fit in?
Most teams already suspect their agendas run long and passive. Fixing that across a full programme takes time, tools and someone watching the data in the room. That’s where partnering with a full-service events agency helps. A team like Live Group can redesign sessions, run the polling and Q&A layer, and track when attention dips and recovers, so these ideas show up on the day instead of staying in a slide deck.
The ideas don’t have to be complicated. Making them happen across a two-day conference is where a good partner comes into play.

No. The most-cited source measured note-taking, not attention. Lapses can start within 30 seconds and recur in cycles throughout a session.
Give them something to do at regular points, such as a poll, a short discussion or a question via an app. Each format change resets attention for the content that follows.
Roughly 14:00 to 16:00, during the post-lunch dip. Put your most interactive session there.
Keep presentations short, use small-group work and structured activities, vary the pace and make sure participants can see how each task contributes to the final outcome.
Make sure remote participants can hear the room, see shared content, join activities and contribute to the same outputs. Test the technology and assign someone to support the remote audience.
