Impostor Hours

There is an hour — mine arrives at about 2am — when the day's evidence gets re-audited by a hostile accountant. Every hesitation is re-examined. Every sentence I said in the lab meeting is played back at higher volume with commentary. The accountant's conclusion is always the same: the admissions committee made a filing error, and eventually someone will notice. I have started calling this the impostor hour. This entry is about the week it ran overtime.

The lab meeting

Some context for readers outside academia: a lab meeting is a weekly ritual where everyone in a research group gathers and one person presents their work while the others eat biscuits and ask questions. The questions are the point. Good questions are how science sharpens itself. Nobody tells you, however, that in your first months the questions will feel less like sharpening and more like being the knife's practice vegetable.

Last Tuesday was my first full presentation — my project plan, my first scraps of data. I had rehearsed for three evenings. I had slides with consistent fonts. And four minutes in, our most senior postdoc asked me, mildly, why I had chosen a sample preparation method that — I am compressing the jargon here — a rival group had shown to be unreliable for exactly my type of measurement, in a paper published eight weeks ago.

I had not read the paper. I did not know the paper existed. The silence that followed had a texture I can still feel on my skin. I said I would look into it, in a voice that arrived from somewhere left of where I was standing, and the meeting moved on, and I spent its remaining fifty minutes composing my resignation in my head in increasingly formal Sinhala.

The 2am audit

That night the accountant worked through till morning. The evidence file was thick: I am the only Sri Lankan in the group. The only one who did her degree outside Europe. The one who says zed and gets a beat of amused silence. Everyone else seems to have read everything, seems to descend from generations of people in white coats, seems to have been issued at birth the confidence I have to assemble every morning from parts. At 2am these facts arrange themselves into a proof. QED: filing error.

The other ledger

Two things happened that week that I am writing down so the accountant has to process them too.

First: I read the paper — properly, twice, with notes. And buried in its supplementary material I found that its unreliable-method result used a different substrate temperature than mine, which means it may not apply to my setup at all. I wrote this up in two careful paragraphs and sent it to the postdoc, braced for dismissal. He replied in nine minutes: Huh. Good catch. Worth checking — want to run it together Thursday? No verdict on my worth. No grade. Just the next experiment. I read that email approximately forty times.

Second: I finally told my supervisor. Not a planned confession — she asked how I was settling in, in her office hour, and the truth got out before security could stop it. I said I felt like everyone else had read everything. She laughed — not unkindly — took off her glasses, and told me about her own first year: she once cited a paper in a group meeting to sound prepared, was asked a follow-up, and had to admit she had only read the abstract. In front of her Nobel-adjacent supervisor. In 1998. She said the memory still visits her at night, and then she said five words I am having framed: Nobody has read everything. Nobody.

Since that conversation I have collected data on what the confident people actually do, and the findings replicate:

• They say “I don't know the answer” roughly daily, without visible injury
• They ask questions I had assumed were too basic to ask aloud
• They google things mid-meeting, unashamed, on the projector screen
• Their first drafts are also terrible; I have now seen the postdoc's

I looked up the research on this feeling, because that is what I do now, apparently. The original 1978 paper called it the impostor phenomenon and — this is the detail that undid me — it was first described in high-achieving women, women who kept attributing their success to luck and error while attributing everyone else's to talent. Half a century later, here I am at a lab bench five thousand kilometres from home, running the same faulty arithmetic. It is strangely comforting, to be so unoriginal. The bug is documented. It ships with the hardware of caring about work you are not yet good at.

The impostor hour still comes at 2am. But I have started leaving evidence out for the accountant: the postdoc's email. Thursday's joint experiment, which is now our experiment. Five words from a woman with a chair and a lab named after no one she apologises to. The audit takes less time now. Some nights it closes early.
