“A really, really excellent lesson. Apart from giving an insight into the ‘Big 5‘, it’s also a dive about what generally constitutes scientific methodology. The topic, which is all but trivial, is explained very concisely and in a way understandable for non-experts. I studied at the ETH Zurich, one of the ‘best’ universities in Europe, and did a PhD afterwards. Thus, I was privileged to have access to a very large selection of great lectures by excellent scholars. Nevertheless, this has certainly been among the best best single lectures I‘ve listened to (in terms of how the material was presented and what I‘ve learned). I‘m very much looking forward to what’s coming next, and I‘m quite certain that it is not only going to be enjoyable but also very valuable for my professional career. P.S. Also great: The access to the audio file, the transcript and the summary of the lesson… Thanks!”
