John L. Ries commented on Karolis Urbonas's blog post How to Lie with Data
"Unless one is deliberately trying to deceive someone else, any false statements made do not constitute lying, but are merely wrong.  On the other hand, technically correct statements made with the intent to mislead are lies (as demonstrated by…"

John L. Ries commented on Vincent Granville's blog post Will Trump Kill Statistician's Jobs
"I doubt that streamlining the process of approving new pharmaceuticals will cost any statisticians their jobs, though the demand might shift somewhat, especially if the job is bungled, requiring consumer advocates, the AMA, and states to do what the…"

John L. Ries replied to Vincent Granville's discussion Detecting Plagiarism with a Simple Trick
"This is made easier by the fact that "invisible" graphics will stick out in a text based browser like a sore thumb (back when I was webmastering, the page wasn't done until it looked good in Lynx).  The trick will catch stupid…"

John L. Ries commented on NYC Data Science Academy's blog post The Pressure Cooker: Population Density and Crime
"I think a large part of the correlation is due to ease of anonymity in urban areas (if people know you, it's a lot easier for them to hold you to account).  The conventional wisdom is that in small towns, everybody knows everybody else,…"

John L. Ries commented on Vincent Granville's blog post Why is Big Data so Dangerous?
"I've been considering writing a satirical advertisement for a political reliability bureau for the past several years (no, I haven't gotten around to it yet): like a credit bureau, but geared toward measuring likely political attitudes so…"

John L. Ries commented on Bernard Marr's blog post 5 Signs That You Are NOT a Data Scientist
"Sorry but science is about knowledge and understanding; not about how businesses can apply it (that is the province of management consultants).  So yes, you can be a data scientist with a purely academic background, just as you can be a chemist…"

John L. Ries commented on Andy Cotgreave's blog post Data without Emotion Doesn't Bring about Change
"Yes, but science is about uncovering truth, which is beyond emotion.  We definitely people advocating for what they think is right (and hopefully, it actually is), but the effort to persuade needs to be kept separate from the efforts to inform…"

John L. Ries commented on Bernard Marr's blog post 10 Big Data Use Cases Everyone Must Read
"On item 2, proceed with caution. It is quite possible that skiiers might want to keep their traditional lift tickets and patronize resorts that offer them as the price of being left alone. If customers see certain behaviors as likely to add to their…"

John L. Ries replied to Sol Lederman's discussion Is there a market for data cleaning professionals?
"Data prep was my specialty for many years and I still do it occasionally.  It is almost always necessary as databases really designed for analysis are rare, there are almost always inconsistencies and typos, and the requisite inspection and…"

John L. Ries commented on Vincent Granville's blog post The 5 Essential Skills Any Data Scientist Needs
"The article appears to be mistitled (probably the title should be "The Five Essential Skills of a Commercial Data Analyst").  While four of the five are useful skills for any scientist and crucial to the statistician (says me,…"

John L. Ries replied to Vincent Granville's discussion Statistician versus data scientist arrogance
"Curiously enough, it seems to me that statistics *is* data science by definition; certainly it has been about making valid inferences from available data since Pascal first started formulating his theories on probability (it's just that early…"

John L. Ries commented on Caitlin Garrett's blog post Five data preparation mistakes
"1. Assuming that your data are consistent. Consistency checks between fields are a must. 2. Using missing value codes as real values. Such codes need to be identified and reset to missing."
