Ipsen treats provided references like a curated Instagram feed and back-channel references (peers, direct reports, people who worked closely) as the real source of truth. She asks pointed, uncomfortable questions, reads pauses as signals, and weights the tightly-worked-with voices heavily while discounting drive-by negativity.
Origin
Lauren Ipsen, from doing reference and back-channel checks across 85+ placements.
Core principles
- 01Provided references are the polished image; back-channels are what peers actually say
- 02No news is not good news — if ten colleagues can't name what someone did, that's a signal
- 03Take every single back-channel with a grain of salt and weigh it holistically
- 04Glaring red flags surface fast; the genuinely hard cases are the 'they were decent' middles
How to run it
- 1
Prefer back-channels over provided references
Lean on peers, direct reports, and close collaborators rather than the references the candidate hands you, which are optimized to impress.
Pro tip Think of it as tagged photos vs. the highlight reel — back-channels show what colleagues actually experienced.
Watch out Provided references almost never come back negative (Ipsen has seen it only twice), so they carry little discriminating signal.

Ask the hard questions
Push past pleasantries: 'Why would I not hire this person? What are their biggest weaknesses? Would you hire/report to/endorse this person if your name was attached?'
Pro tip When you get a soft 'they work too hard,' respond 'no, tell me more — what are their actual weaknesses?'

Read the pauses
Watch for the slightest hesitation — even a small pause is enough to make you think twice and probe further.
Pro tip It's a lot of reading the room and probing harder than feels necessary.

Weight and triangulate the signal
Discount people who are negative just to be negative (and remember the person you're calling may have been back-channeled by the candidate too). Concentrate on those who worked super closely to judge the ambiguous 'decent' cases.
Pro tip Tap your own trusted contacts inside academy/great companies to point you at the three best people, so you skip back-channeling the middle 50%.
Watch out Polarizing individuals and clear bad actors surface quickly; the mixed 'I think they were decent' verdicts are the hardest and need the closest collaborators to resolve.
In the wild
Ipsen says if she calls ten people from someone's org during a given period and none can speak to anything the person did, 'no news is not necessarily good news' — you want to hear specific X, Y, Z accomplishments.
→ Silence about impact functions as a soft negative signal, steering her away from candidates with no traceable fingerprints.
Common mistakes
Relying on candidate-provided references
They are curated to impress and almost never come back negative, so they provide little discriminating information versus peer back-channels.
Accepting the 'works too hard' non-answer
Treating a canned strength-disguised-as-weakness as a real answer skips the actual weaknesses you need to be cognizant of.
Is it for you?
Best for
Recruiters and hiring managers doing due diligence on senior leadership candidates
Not ideal for
Junior or high-volume hiring where deep back-channel networks per candidate aren't feasible
From the transcript
“back Channel references I think will always provide a greater source of Truth than provided”
“why would I not hire this person what are their biggest weaknesses”
“even if you just sense the slightest pause that in itself will be enough to to kind of make you think twice”
“if I call 10 people that were a part of the same organization as someone during a given period of time and they can't speak…”
“similar to like an Instagram reel as opposed to the photos you're tagged in”
