Some of this is folk wisdom and some of it has actual research behind it. The gap between the two is worth knowing.
A Note on Generalising
Plenty of men notice everything below and plenty of women notice none of it. What follows is what comes up repeatedly in surveys, in dating research and in the accounts people give afterwards, not a law of nature. Read it as a checklist rather than a theory of gender.
How You Treat the Waiter
The oldest observation in dating and still the most reliable. Being warm to a date while being curt to whoever brings the drinks reads as a performance rather than a personality, and it is the single most commonly cited dealbreaker in first-date surveys. Nobody being rude to a waiter thinks they are being rude.
Whether You Ask Follow-Up Questions
Harvard research led by Karen Huang found that people who ask more questions, and particularly follow-up questions, are better liked, and that in speed-dating data question-askers were more likely to get a second date. Following up on an answer signals you were listening. Moving to your next topic signals the opposite.
The Phone on the Table
Research by Przybylski and Weinstein found that simply having a phone visible during a conversation reduced how close and trusting people felt, even when nobody touched it. Face down is not neutral. In a pocket is neutral.
Your Hands and Nails
Hands are at eye level for most of a meal, which is why they get noticed. Trimmed, clean nails cost nothing and register immediately. This is consistently among the most reported details and consistently among the least considered by the person being looked at.
Your Shoes
A 2012 study by Gillath and colleagues found people could judge some personality characteristics from photographs of shoes at above-chance rates. Whether or not that finding is robust, the folk version is real: shoes get looked at, and condition matters far more than cost.
Scent, and Especially Too Much of It
Olfactory fatigue means you stop smelling your own fragrance within about fifteen minutes, so the man wearing far too much is genuinely unaware. Sitting across a small table amplifies everything. Three sprays is plenty and clean beats fragranced.
Whether Your Story Has a Point
Long anecdotes without a destination are noticed early and remembered afterwards. It is less about talking too much than about not checking whether the other person is still with you, which is a thing people can feel happening.
What You Say About Your Ex
Almost everybody mentions a former partner at some stage and the content matters less than the temperature. Neutral is fine. Bitter is not, and neither is bringing them up repeatedly, which reads as unfinished business regardless of what is being said.
Punctuality and How You Handle Being Late
Being late is forgivable and universal. Not texting is the part that registers. The message costs ten seconds and it is read as information about how you treat people generally rather than about traffic.
Whether You Have a Plan
Not an elaborate one. Having chosen a place, knowing roughly how the evening might go, and being willing to decide something. Deferring every decision reads as indifference even when it is meant as politeness, which is one of the more common misfires.
The Gap Between Your Words and Your Face
People are fairly good at spotting incongruence between what someone says and how they say it, an effect studied under the heading of thin-slice judgements. Enthusiastic words delivered flatly land as insincere, and most people cannot say why they felt that.
Small Consistency Details
Whether the version of your job matches what you said in messages, whether the age matches the photos, whether the story shifts slightly. Nobody is running an investigation and the discrepancies get logged anyway, and they colour everything afterwards.
What This Actually Adds Up To
Almost none of it is about looks and almost all of it is about attention. Turning up on time, asking a second question, putting the phone away and being decent to staff covers the overwhelming majority of it, and all four are entirely within anybody’s control.
