- The two-second rule is really critical. A famous Harvard experiment shows that the impressions we get in seeing two seconds of someone - without even any sound - correlate almost exactly with the impression we get from being taught by them for a whole semester.
- Signalling overcomes information asymmetry. The successful candidates were confident and this is our natural way of signalling that we're good at something - which is what people need to know when they're evaluating us.
- Figures are always approximate. Yasmina's 8% discrepancy in her turnover figures makes no difference at all to anyone in the real world. Claude tried to bring a hyper-rationality to the interview process which is counterproductive.
Check back at 8.00 tonight - not 9.00 - for live coverage here. There's an extra programme at 8 which profiles the five remaining candidates, so switch on your TV early. We'll be covering that programme as well as the main episode.
And while we're mentioning it, the grand final is not next Wednesday but this SUNDAY, 7th June, because of the England-Andorra football match on Wednesday. So a few days less of waiting around to get it over with (and hasn't it been a long, long time?)
As always we'll cover the economic theory that is revealed by the programme - in this case a bit of labour economics, some search theory and some intriguing behavioural theory - for instance the experiment that demonstrated people make incredibly accurate predictions from the first 2 seconds of meeting someone (or that their prejudices are entrenched within that period).
Look forward to talking with you all tonight.
