Canadian researchers have found the first evidence that older brains get more benefit than younger brains from learning information the hard way - via trial-and-error learning

In Innovation Deep Dive, Lisa Strausfeld from Pentagram has contrasted the drivers and the impact of innovation of various countries by way of an interactive line ranking. The visualization uses quite a large set of different datasets, ranging from Gallup and business schools reports, to the usual suspects like the UNESCO and the World Bank. The interface requires some trial-and-error to get used to (e.g. the data categories at the top are clickable), but creates a compelling overview of how different nations actually perform versus how their business executives perceive the same issue.

Feedback loops are how we learn, whether we call it trial and error or course correction. In so many areas of life, we succeed when we have some sense of where we stand and some evaluation of our progress. Indeed, we tend to crave this sort of information; it's something we viscerally want to know, good or bad. As Stanford's Bandura put it, "People are proactive, aspiring organisms." Feedback taps into those aspirations. But maybe requiring people to do a little work-to stick accelerometers around their house or plug a device into a wall socket-is just enough of a nudge to get our brains engaged in the prospect for change.
