Presenting Research to the Deputy Prime Minister

You get four minutes. Sometimes five.

Standing in front of a poster with Deputy Prime Minister Heng Swee Keat, the calculus of communication compresses sharply. Every slide-decks-worth of detail you carried into the room has to collapse into three sentences before he turns to the next booth.

What surprised me was how useful the constraint is.

The discipline of compression

Engineering students are trained to lead with the apparatus. Here is the column. Here is the flow path. Here is the sorbent bed. Here is the breakthrough curve. The story is bottom-up — physics, then process, then implication — because that is the order in which we built our understanding.

A policy audience runs the other direction. They want the implication first. What does this mean for Singapore? If the apparatus is needed, it is needed to support the implication, not to precede it.

I rewrote my elevator pitch four times the night before. The final version started: "Direct Air Capture is the only carbon-removal technology that scales independently of point sources. The sorbent is the cost driver. We are studying a class of polymer sorbents that may halve the regeneration energy."

Three sentences. The apparatus comes after, only if asked.

The question behind the question

DPM Heng asked, after a moment, "and how confident are you in the energy claim?"

This is the policy version of a research question. The technical version is: what is the regeneration enthalpy of your formulation, what fraction is recoverable, and what is the integrated energy cost per tonne CO₂ removed? The answer to the technical question is "we are still measuring." The answer to the policy question is "we have an early signal that this class of sorbent regenerates at lower temperature than amine-grafted silica, and we will know within six months whether that translates into the energy claim."

Same finding. Different framing. Both are honest. The second is useful in the room you are standing in.

What I am taking forward

Three habits.

1. Lead with the implication, support with the mechanism. Even in a research seminar. The audience has a finite attention budget and you have a strong incentive to spend it on the part that earns the next conversation.
2. Calibrate confidence in the audience's vocabulary. "p < 0.05" means something to a statistician and nothing to a minister. "We are confident enough to recommend a six-month follow-up study" means something to both.
3. Practise the four-minute pitch as if it were the only one. Because in a room full of booths, it is.
