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.
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
It was strange, in a way, because there were no ideas involved in the laser that weren't already known by somebody 25 years before lasers were discovered. The ideas were all there; just, nobody put it together.

Almost any questions can be answered,cheaply, quickly and finally, by a test campaign. And that's he way to answer them - not by arguments around a table
Theoretical physics is one of the few fields in which being disabled is no handicap - it is all in the mind.
I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness.
