 Hi everyone and welcome to module 1. This week we will focus on two things. First, what is big data? This is the introduction to the course. We want to understand the question because it is relevant for our purposes later. There is no reading for this part, but please view the PowerPoint under the lecture tab and watch the videos that are embedded in the lecture. This introduction is not graded, but it isn't necessary to be thinking about for the rest of the summer and throughout this course. After the introduction, the first module, Predictable Irrationality, focuses on the ways we think, process, and make decisions. What does this process look like? How does our thought process really operate? To do this, we focus on readings from the evolutionary psychology field and behavioral economics. Please do the readings and view the lecture, which also has videos embedded in it. Further, there's a test I would like you all to take. It is called the IAT test or the Implicit Association test. The instructions for the test are in the lecture PowerPoint. As always, if you have any questions, feel free to reach out. Don't forget, discussion poster due at 11.59 p.m. on Thursday and the assignment for this first module is due at 11.59 p.m. on Sunday.
