A hypothesis is an assumption, something proposed for the sake of argument so that it can be tested to see if it might be true.
In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review. You ask a question, read up on what has been studied before, and then form a hypothesis.
A theory, in contrast, is a principle that has been formed as an attempt to explain things that have already been substantiated by data. It is used in the names of a number of principles accepted in the scientific community, such as the Big Bang Theory. Because of the rigors of experimentation and control, its likelihood as truth is much higher than that of a hypothesis.

Traditional economics views humans as robotic machines who make calculated decisions based on logic. In contrast, behavioural economics views humans as irrational and emotional beings who are influenced by biases and experience when making decisions. This infographic takes a closer look at just what behavioural economics is and how it can be used.

Anyone who’s got a formal education in economics knows who Hal Varian is. He’s most popularly known for his book Intermediate Economics. He’s also the Chief Economist at Google. He is known to have famously stated more or less, that statisticians and data analysts would be the sexiest jobs of the next decade.
That has come true, to a great extent, and we’ll be seeing more.
In a paper called ‘Big Data: New Tricks for Econometrics‘, Varian goes on to say that:
In fact, my standard advice to graduate students these days is “go to the computer science department and take a class in machine learning.” There have been very fruitful collaborations between computer scientists and statisticians in the last decade or so, and I…

There’s always going to be space for reading, curating and cheering on others’ work. But there should also be a space for building on it and creating stuff of one’s own. Each of us has something to say, and we have the responsibility and privilege of adding to the discourse. It’s up to us to find and nurture the right balance and feel inspired by—not intimidated by–the work that others do. After all, everything is a remix.
I have a lot of ideas in my head. And for the most part, that’s where they used to stay.
In my head. Where other people couldn’t see them, interact with them or build upon them. Where they were safe and untested and uncriticized. All mine.
Sure, I’ve created some. Some might say I’ve created plenty. But that’s only because they can’t see what I’m not creating. For example, this very post sat dormant for at least a month while I pondered, waited and nitpicked at it.
Because the riskiest, most dangerous and potentially most interesting ideas are the easiest to hold back. I would pin them down like butterflies on a mat, like art at a museum. They were in spreadsheets, in notebooks, on scrap paper around my desk.
And while it might feel creative to think of these ideas, they were dying a lonely death when I…
