learning, emoji, bayesian or frequentist

The scientific research on learning styles is “so weak and unconvincing,” concluded a group of distinguished psychologists in a 2008 review, that it is not possible “to justify incorporating learning-styles assessments into general educational practice.” A 2010 article was even more blunt: “There is no credible evidence that learning styles exist,” wrote University of Virginia cognitive scientist Daniel Willingham and co-author Cedar Riener. While students do have preferences about how they learn, the evidence shows they absorb information just as well whether or not they encounter it in their preferred mode.

Follow the way of the emoji and you will mourn the moment when you finally open your heart to the person who has meant the most to you. But you will also learn how much easier it is to get out of an unwanted date (flames + person running + heart broken in two), resign from a rubbish job (paper and pencil + briefcase + lit bomb + pink-sweater-girl waving goodbye + wine) or arrange to go out on the town (multiple possibilities, suggesting that this is what it's all about). Roland Barthes would have had a field day.

You have a coin that when flipped ends up head with probability [Math Processing Error] and ends up tail with probability [Math Processing Error]. (The value of [Math Processing Error] is unknown.)

Trying to estimate [Math Processing Error], you flip the coin 14 times. It ends up head 10 times.

Then you have to decide on the following event: "In the next two tosses we will get two heads in a row."

Would you bet that the event will happen or that it will not happen?
