Tip of the day: don’t be Theranosed

May 23, 2016

Theranos (v): to spin stories that appeal to data while not presenting any data To be Theranosed is to fall for scammers who tell stories appealing to data but do not present any actual data. This is worse than story time, in which the storyteller starts out with real data but veers off mid-stream into unsubstantiated froth, hoping you and I got carried away by the narrative flow. Theranos (n):…

Law versus ethics: how the new overtime pay rule will play out

May 18, 2016
By

In any discussion of ethics , someone is bound to bring up the law: it is okay to do something if something is not against the law. The logical conclusion of this belief is that ethics is irrelevant in the presence of the law. The recent stories relating to minimum wage and the overtime pay rule changes (for example, link) argue strongly against such a point of view. The law…

Dreadful analysis shows the importance of numbersense

May 9, 2016
By

Last year, Gizmodo capitalized on the fallout from the Ashley Madison hacking scandal and published a sensational article claiming the website that, if you haven't heard, promotes adultery, has "almost no" real women on it. The subtext is that millions of gullible, disloyal males were paying monthly fees to the website to do nothing or, cue the laugh track, to converse with "badly-designed robots." These men, according to Gizmodo, were…

(By the way, if you are at the INFORMS Analytics Conference in Orlando, come and find me. I am speaking on Ethics on Tuesday morning.) I told the students that it is not too early to…

In the last post in the Know Your Data series, I discussed how Uber can use its vast database of your personal trips against your personal interests. (This does not preclude the possibility that they use the data for your benefit.) It turns out that something more ominous is at foot… a number of news outlets have just published investigative reports about a company known as Vigilant Solutions (EFF, The…
