Posted on by Ville Miettinen

… world’s poorest children.

In a (very entertaining) TED talk, Professor Mitra discusses his experiments in “self-learning”. His first scheme was setting up “hole in the wall” computers in villages in rural India. Machines were installed on the streets, raised about a meter off the ground. Groups of kids spent hours figuring out how the computers worked – often managing to teach themselves English in the process.

Crowd Labs Incorporated

Posted on by Ville Miettinen

… scientists, psychologists and economists constantly require thousands of people to take part in experiments. Trouble is, running a lab is expensive: assistants to pay, participants to hunt down and schedules to organize. Compare that ( as Lauren Schmidt did at CrowdConf this year ) to crowdsourced labor: a global pool of potential subjects who’ll work for a fraction of the price, and don’t need travel expenses.

It’s a concept the research community is just beginning to get behind. …

… equivalent of pedigree dog breeding. A 7,000-strong crowd formed the judging panel for the initial experiments, and has so far taken the music through over 2,500 generations.

The first generation of loops was randomly generated, and barely sounded like music at all. But as the crowd selected loops which contained pleasing chords or sequences of notes, tunes began to emerge. Soon, the randomly generated sounds had become music, with popular melodies or chords surviving through the generations …

Confidence tricks: can crowdsourcing keep our feet on the ground?

Posted on by Ville Miettinen

… psychologists Justin Kruger and David Dunning may explain why we get it wrong so often.

Their experiments revealed that people generally overestimate their ability in areas they understand poorly, and underestimate their ability where their understanding is good. This is known as the Dunning-Kruger Effect, and is one of many cognitive biases that affect us all.
