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.
If I have put the case of science at all correctly, the reader will have recognised that modern science does much more than demand that it shall be left in undisturbed possession of what the theologian and metaphysician please to term its 'legitimate field'. It claims that the whole range of phenomena, mental as well as physical-the entire universe-is its field. It asserts that the scientific method is the sole gateway to the whole region of knowledge.
When I meet God, I am going to ask him two questions: Why relativity ? And why turbulence ? I really believe he will have an answer for the first.
Science should be the most fun job on the planet. You get to ask questions about the world around you and go out and seek the answers. Not to have fun doing that is crazy.
The function of muscle is to pull and not to push, except in the case of the genitals and the tongue.
In more than one respect, the exploring of the Solar System and homesteading other worlds constitutes the beginning, much more than the end, of history.
Opponents say natural selection is not a theory supported by observation or experiment; that it is not based on fact; and that it cannot be proved. Well, no, you cannot prove the theory to people who won't believe in it any more than you can prove that the Battle of Hastings took place in 1066. However, we know the battle happened then, just as we know the course of evolution on earth unambiguously shows that Darwin was right.
