Every session on the three ESOMAR Congress 2026 livestreams that carry captions: what each one reported, a short quote, and every figure quoted from the stage, each linked to that moment in the video.
Not the whole congress. One livestream of about 4h27m has no captions on YouTube (checked again on 10 September), so it is missing here; the stream itself is still watchable. Some sessions also ran in rooms that were not on these streams: a panellist on day two refers to a debate "in the neighbouring room". Treat counts on this page as counts of what was transcribed.
The 90% club
Every accuracy or agreement figure given from the synthetic data stage, placed on one scale. Each measures something different against a different referent, so reading across the rows is exactly the comparison the figures do not support.
Reading: the only human benchmark offered all day is that two panels running the same survey agree 85 to 90%. Most results sit in or just above that band, but one is a share of preferences overlapping, one is normalised by respondents' own test-retest consistency, and one is a proprietary index. The "Columbia study" figure cited as 87% should be checked against the published paper before anyone repeats it.
Each figure is matched character for character to a caption line. The italic line under each is that caption, garbling included.
| Session | Figure | What it measures | Compared with | Kind | Video time |
|---|
| Stream | Day | First caption | Last caption | Span | Words | Breaks over 5 min |
|---|
Each video starts with pre-roll before the first caption, not counted here. Day labels come from the stage: the afternoon chair says "what a way to close day one", the day two chair says "the second day", and a finalist says she will present "on Friday". The venue lists the congress as 1 to 4 September. The missing stream being day three is likely, not confirmed.
Stream links were matched by timestamp. The day 1 morning link was saved at 45:05, two seconds after that stream's first caption. The day 2 link was saved at 3:47:15, as the Accenture synthetic data talk begins, and only the day 1 morning and day 2 streams run that long. The day 1 afternoon link is matched by elimination.
