The single most effective CPD marketing mechanism in the AEC sector is the provision of free food. This isn’t a complaint. It’s a rational response to an information-poor environment, and worth taking seriously rather than dismissing as evidence that professionals don’t care about content quality.
Why the free lunch works.
When quality signals are absent — and in most CPD contexts, they are — and attendance costs something real in time and commute, incidental benefits legitimately influence the decision to attend. A professional deciding whether to give up an hour of billable time to attend a session has almost no reliable way of knowing, in advance, whether that session will be worth the hour. Accreditation tells them the session met a content-relevance threshold, not that it’s any good. A title and a provider name tell them very little. In the absence of any signal that actually predicts value, a free lunch is not a distraction from the decision — it’s one of the only pieces of information in the decision that’s concrete and verifiable in advance. You know the sandwich will be good. You don’t know if the content will be.
This is a market failure, not a character flaw.
It’s tempting to read the Lunch & Learn phenomenon as evidence that professionals are shallow, or that providers who lean on catering are cynical. Neither reading is quite right. Providers offer lunch because it reliably drives attendance, in a market where nothing else reliably signals quality to a prospective attendee. Professionals accept the trade because, absent better information, an hour spent somewhere with decent food and mediocre content is not obviously worse than an hour spent somewhere with an unknown quantity of both. Behavioural economics has a name for decision-making under exactly this kind of uncertainty: when the outcome that matters most can’t be evaluated in advance, decision-makers reasonably weight the inputs they can evaluate. The lunch isn’t crowding out a rational decision. It’s filling a gap where a rational decision has nothing else to work with.
What would actually change the dynamic.
The Lunch & Learn will persist for exactly as long as outcome measurement is absent from the CPD market — not because professionals prefer catering to content, but because catering is currently one of the few pre-attendance signals available at all. Once a professional can see, before committing an hour, whether a given session has historically produced attendees who reported changing their practice as a result, the free lunch stops being one of the only available signals and becomes what it always should have been: a nice bonus, not a substitute for information about whether the hour will be worth it. This doesn’t require anyone to stop serving lunch. It requires a second signal to exist alongside it.
Taking it seriously.
None of this is written to shame anyone attending CPD for the sandwiches, or providers for offering them. It’s written to name, plainly, what’s actually happening in the decision to attend — and to point out that the fix isn’t asking people to care more about content in the abstract. It’s giving them something concrete to weigh the sandwich against.
FAQs
In a market where nothing reliably signals whether a CPD session will be worth attending, a free lunch is one of the few things a prospective attendee can evaluate in advance with certainty. It’s not that professionals value catering over content — it’s that catering is verifiable and content quality currently isn’t, until you’ve already sat through the session.
No. It means that, absent a reliable pre-attendance signal for content quality, other verifiable factors — including catering — legitimately influence the attendance decision. This is a standard response to decision-making under uncertainty, not evidence of indifference to quality.
A pre-attendance signal that reliably predicts whether a session produces practice change — something a prospective attendee could weigh alongside the catering, rather than in the absence of any alternative. Once that signal exists, free lunch becomes a bonus rather than one of the only available decision inputs.
“Outcome signal is the thing that changes this dynamic. It exists now.”
