In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
I recently read this interesting, and distressing, story of a man who was drugged and robbed. A form of crime which has been going on for centuries. But the 21st Century twist is that the thieves forced him to transfer large sums of money via his phone's banking apps.
While under the influence, the victim used his usernames, passwords, PINs, and biometrics to send money to the criminal's accounts.
Is there a "technological" way to stop this? His banks initially refused to refund the stolen money. Only once the press stepped in did they relent. One bank, Revolut, said:
This was an unusual case where the payments were authorised by the customer but, as is now clear, without his consent.
