LabCoat Leni Answers

“Leni is a budding young scientist and he’s fascinated by real research. He says, ‘Andy, man, I like an example about using an eel as a cure for constipation as much as the next guy, but all of your data are made up. We need some real examples, dude!’ So off Leni went: he walked the globe, a lone data warrior in a thankless quest for real data. He turned up at universities, cornered academics, kidnapped their families and threatened to put them in a bath of crayfish unless he was given real data. The generous ones relented, but others? Well, let’s just say their families are sore. So, when you see Leni you know that you will get some real data, from a real research study to analyse. Keep it real.”
