He’s probably the first person ever to lose his job because of his Harvard PhD dissertation.
The 'he' here is Jason Richwine, one of the authors of a recent Heritage Foundation report on immigration reform that has been getting some serious backlash.
Here's the quote again, with some context:
He’s probably the first person ever to lose his job because of his Harvard PhD dissertation: Jason Richwine, let go by the Heritage Foundation on Friday. The problem: he co-authored their position paper opposing immigration reform; and then somebody discovered that his PhD thesis at Harvard’s Kennedy School was dedicated to the proposition that Hispanics have lower IQs than white people. Not even the Heritage Foundation wanted to go there–so after two days trying to answer embarrassing questions, he left quietly.
But how did he get a Harvard PhD for work that even the Heritage Foundation wouldn’t accept?
Jon Wiener's post also expands a bit on the bad uses of IQ tests. Inside Higher Ed reports that the revelations about Richwine's thesis has led to quite a ruckus at Harvard itself, where student organizations have "[have questioned] the legitimacy of the dissertation that was awarded to Richwine".
Noah Smith at Noahpinion: If you get a PhD, get an economics PhD.
... [D]espite these caveats, the econ PhD still seems like quite a sweet deal to me. And compared to a hellish, soul-crushing, and economically dubious lab science PhD, econ seems like a slam dunk. There are very few such bargains left in the American labor market. Grab this one while it's still on the shelves. [Bold emphasis added]
Sabine Hossenfelder (aka Bee)at Back Reaction : What do "most physicists" work on?
Since coverage by the media is driven by popularity and not by relevance, one can expect such a skewed representation. It probably isn't much different in other areas of our lives. (Who actually wears those wacky clothes that fashion designers celebrate?) What bothers me much more than the skewed selection of topics is how their relevance is misrepresented even in these articles. I must have read hundreds of times that "many physicists" believe this or that, while in reality most physicists couldn't care less and probably have no opinion whatsoever.

Heritage Foundation has stepped in it again, with a "report" on immigration reform [see Krugman's post]. It has led to one good thing, though: we get to revisit the topic of what IQ is and what it is not. Two links:
James Heckman (1995): Lessons from the Bell Curve [pdf].
As the day [of my presentation in the seminar class on topology] approached, I began to panic. I called my dad, a warm and gentle soul. It didn’t help. I called my sister, a math educator who always lifts my spirits. It didn’t help. Backed into a corner, I scheduled a meeting with the professor to throw myself at his mercy.
I was sweating in the elevator up to his office. The worst thing was that I admired him. Most world-class mathematicians view teaching undergraduates as a burdensome act of charity, like ladling soup for unbathed children. He was different: perceptive, hardworking, sincere. And here I was, knocking on his office door, striding in to tell him that I had come up short. An unbathed child asking for soup.
Teachers have such power. He could have crushed me if he wanted.
He didn’t, of course. [...] [Bold emphasis added]

Let me share some pertinent thoughts in public domain stemming from personal association. The text is modified from another one I was asked to write on him on another occasion.
I was a Teaching Assistant for Prof. Jack Holman all the four years while pursuing my Ph. D. at SMU (1998 - 2002). Once during a discussion with him, I goofed on an explanation about how friction power affects the efficiency of an internal combustion engine (of our cars). At the end of my explanation I raised a doubt, which wouldn't have been there had my understanding been correct. He didn't answer or correct me immediately. "Let me know if you find the answer" is all he said. I found the answer and went to him to apologize for my wrong understanding. "There, you seem to know something now, don't you," came the reply with a beaming smile and a penetrating look above his spectacle rim.

Here's The Onion's take on student evaluations: Professor Deeply Hurt by Student's Evaluation. The Dean's comment comes right at the end, but it's brilliant:
“Students and the enormous revenue they bring in to our institution are a more valued commodity to us than faculty,” Dean James Hewitt said. “Although Rothberg is a distinguished, tenured professor with countless academic credentials and knowledge of 21 modern and ancient languages, there is absolutely no excuse for his boring Chad with his lectures. Chad must be entertained at all costs.”
Could this phrase include acts that are meant to hurt a colleague's professional standing? Could someone be fired for this offence? The University of New Hampshire said yes, and yes.
Marco Dorfsman, a Spanish professor at UNH, tampered with student evaluations of an unnamed colleague. He was reported to have come clean in an e-mail to his colleagues about 10 days ago, and the university fired him last week. From the university's statement:
Dorfsman admitted to intentionally lowering the student evaluations of another faculty member. [...]
The [Professional Standards Committee] members unanimously agreed that Professor Dorfsman’s conduct constituted moral turpitude and ‘evinces a gross disregard for the rights of others, is a clear and intentional breach of duties owed to others and to the university by virtue of employment at UNH and membership in the procession, in which such an act is considered contrary to the accepted and expected rules of moral behavior, justice or honesty, and evokes condemnation. [...]
According the CHE note, 'moral turpitude' became a fireable offence at UNH just last year.

Two NPR stories on women in computer science: Blazing The Trail For Female Programmers and How One College Is Closing The Computer Science Gender Gap.
Our Institute, the Indian Institute of Science, started a 4-year BS degree program in 2011, the same year in which IIT-K dumped the 5-year integrated MSc program in favour of the 4-year BS (though the MSc program survives in the form of a BS-MSc combo for those who opt to spend an extra year). Bangalore University's also started its 4-year bachelors program around that time.
The Delhi University is starting, this July, its own version of a 4-year bachelors program, not just in the sciences, but in all fields. Unlike the earlier episodes in which discussions on the new program were confined to the institutions themselves, the DU initiative is being debated openly in many public forums; see, for example:
How to Destroy a University by Jayati Ghosh, and a response entitled Why Delhi University’s four-year degree is a good idea by Chandrachur Singh.
Why Delhi University’s Four Year Undergraduate Programme Should Not be Implemented with Irresponsible Haste by Apoorvanand, who also penned an earlier op-ed entitled Du's 4-year degree course: Reforms at Reckless Speed.
On Rahul Siddharthan's blog: How not to modernise a university: Dinesh Singh’s ham-handed efforts at reform, a note from the faculty of St. Stephen's College's physics department (and Rahul's comments appear at the end).
[Aside: Though the authors don't mention the 4-year degree course, I read this December op-ed entitled Wanted: intellectual leaders, not CEOsop-ed by Apoorvanand and Satish Deshpande as at least partly informed by the way this issue was being handled by the DU vice chancellor.]
On the practical side, I am not persuaded by the "things are getting implemented in haste" argument. I have seen quite a few episodes in recent years when new things -- right from creation of new institutions such as IISERs, IITs, IIMs, and new Central Universities, to OBC reservation in centrally funded institutions, to "doing something about entrance exams" ;-) -- got implemented after some debate, but with seriously inadequate preparation. Let's face it: if the leadership wants a certain change, and if it feels the time is ripe, it will get it done immediately.
It is important that answers be found for practical questions such as "Does the UGC recognize the BS degree?", "Will the BS graduates need a one-year or two-year masters to be treated as equivalent to the MSc graduates?", "What about those who leave with a diploma-type certificate after two years?". But we should be careful not to overstate their importance. The key, I think, is that these questions raised by the critics can be answered over the next 2 to 4 years, during which UGC can be made to take a call on these and other similar questions [If the IITs, IISc and DU cannot manage this, I don't know what will].
Similarly, incremental solutions, including mid-course corrections to address the curriculum-related issues highlighted by the St. Stephen's faculty, over the next several years will see DU through to its new equilibrium.
For outsiders like us, the more relevant part of the debate is about whether this transition from a 3-year BSc to a 4-year BS program is good and desirable. I answered yes to this question a long time ago; one of the reasons being it brings science and arts students on par with engineering students who get their degree in 4-years (in our current wretched system, only MSc degree holders are treated as equivalent to BE/BTech graduates). I also like the way DU's program offers exit options at the end of the 2nd year (with a diploma-like certificate) or the 3rd year (with a BSc degree).
All this is not to deny the distinct impression that the DU administration has made serious missteps. The final product appears not to have much to do with the big ideas which were used to sell the program to the constituent colleges and their teachers; for example, the inflexible curriculum is a cruel blow, especially since the entire 4-year program was sold using flexibility as a central feature.
While these missteps need not be deal-breakers, any corrective measures (in the medium and long term) to improve the program will require the DU administration to listen to the critics with an open mind; what the current debate shows is that it lacks this crucial skill.

The Data Stories blog has a great interactive infographic on a grim, but all too real, phenomenon that goes by the name "missing women". The post is triggered by a recent paper in EPW by Siwan Anderson and Debraj Ray who went beyond sex-selective abortion and infanticide to examine data on women's "excess mortality" across all age groups in India [The authors have presented summary at the Ideas for India site, which I linked to sometime ago].
Here's a short description of the infographic:
The paper calculated the numbers for 2003. I’ve redone the numbers to calculate excess female deaths per thousand across age-groups for India, China, and a number of Indian states [specifically, Haryana, UP, Kerala, Bengal, Bihar, and "Others"] for 2010. Each bar shows excess mortality per 1000 women in that age-group only.

A great story from Reuters: How a student took on eminent economists on debt issue - and won. The student is Thomas Herndon, in the UMass grad program in economics. This thing is buried deep inside the report, but worth highlighting:
Herndon's paper began life as a replication exercise for a term paper in a graduate econometrics class.
