The problem with data is that it says a lot, but it also says nothing. 'Big data' is terrific, but it's usually thin. To understand why something is happening, we have to engage in both forensics and guess work.
Interpretation
Data can provide insights but also lead to confusion if not interpreted correctly. Understanding data requires analytical skills and intuition.
This quote by Sendhil Mullainathan emphasizes the dual nature of data, illustrating that while it can offer extensive information, it often lacks depth without proper interpretation. He suggests that in order to truly grasp the causes behind data trends, one must employ both forensic analysis and intuitive guesswork, indicating that raw data alone is insufficient for understanding complex phenomena.
In practice
This quote can be used in a presentation about the challenges of interpreting data in business analytics.
Economists specialize in pointing out unpleasant trade-offs - a skill that is on full display in the health care debate. We want patients to receive the best care available. We also want consumers to pay less. And we don't want to bankrupt the government or private insurers. Something must give.
Faced with a time shortage, we squeeze tasks into the nooks and crannies of our calendar, leaving less and less time to switch between them. As a result, we become less and less productive exactly when we need to be most productive.
There's a popular image of people who don't save for the future as lacking in self-control. But the reason saving is so hard has less to do with self-control and more to do with a scarcity of attention.
January is always a good month for behavioral economics: Few things illustrate self-control as vividly as New Year's resolutions. February is even better, though, because it lets us study why so many of those resolutions are broken.
Busy people all make the same mistake: they assume they are short on time, which of course, they are. But time is not their only scarce resource. They are also short on bandwidth. By bandwidth I mean basic cognitive resources - psychologists call them working memory and executive control - that we use in nearly every activity.
I am mindful that scientific achievement is rooted in the past, is cultivated to full stature by many contemporaries and flourishes only in favorable environment. No individual is alone responsible for a single stepping stone along the path of progress, and where the path is smooth progress is most rapid. In my own work this has been particularly true.
Science has always been my preoccupation and when you think a breakthrough is possible, it is terribly exciting.
With a few honorable exceptions the press of the United States is at the beck and call of the patent medicines. Not only do the newspapers modify news possibly affecting these interests, but they sometimes become their agents.
It is a curious historical fact that modern quantum mechanics began with two quite different mathematical formulations: the differential equation of Schroedinger and the matrix algebra of Heisenberg. The two apparently dissimilar approaches were proved to be mathematically equivalent.
It is remarkable, Hardin, how the religion of science has grabbed hold.
I am not accustomed to saying anything with certainty after only one or two observations.
