In “Intensive, Early Therapy Helps Children with Autism Improve Communication Skills,” Nicholas Lange and Christopher J. McDougle refer to autism as a “disorder” to be cured. But what if children with autism don't see it like this? Perhaps, for them, it is a way of going through the world, neither inferior nor superior to any other.
In “Adobe’s Software Subscription Model Means You Can’t Own Your Software” [TechnoFiles], David Pogue laments that large software companies such as Adobe and Microsoft are switching to a subscription model for their programs. Let's not pretend that we have ever owned these applications. We merely pay for a license encumbered with restrictions on installations, inspection and manipulation.
GUNS AND VIOLENCE
In “Why We Should Choose Science over Beliefs” [Skeptic], Michael Shermer asserts that I have practiced “cherry picking and data mining of studies to suit ideological convictions” in my arguments that private gun ownership reduces violent crime. Like Shermer, my views on guns have changed over time. He ignores that, as I have shown in More Guns, Less Crime (third edition, 2010), the large majority of peer-reviewed studies demonstrate right-to-carry laws reduce crime and background checks do not.

SHERMER REPLIES: The gun-control issue is one of the most complex I have ever encountered. So much data and so many variables affect the outcome of gun-control laws that one can easily make the data come out either in support of or against such measures. From the studies I have read (and cited in my debates with Lott), such proposed measures as background checks, assault weapon bans and magazine size restrictions could help reduce America's death rate from guns (more than 10 per 100,000), which is almost an order of magnitude higher than that of most European nations. I did read Lott's book. But I also read a scholarly analysis of it called “Shooting Down the More Guns, Less Crime Hypothesis,” which is available for free at www.nber.org/papers/w9336.
“Renewable Energy's Hidden Costs,” by John Matson [Graphic Science], did not specify the low-end estimate for wind energy's greenhouse payback time, which is less than one year and is more reflective of modern wind turbines.
“Gravitational-Wave Detectors Get Ready to Hunt for the Big Bang,” by Ross D. Andersen, asserted that gravitational waves are “impervious to the astrophysical giants in their path”; they are nearly impervious. Gravitational waves are much more impervious than light waves are, but they can be affected by massive cosmic structures.
“Russia’s Nuclear Reactors Could Take over the World, Safe or Not,” by Eve Conant, stated that TerraPower in Bellevue, Wash., is developing fast mini reactors and that it tests its prototypes in a Russian facility in Dimitrovgrad. TerraPower's fast reactors do not qualify as “mini,” and it is testing nuclear materials, not prototypes, at the Russian facility. Also, the article referred to VVERs as being housed in a containment building. It should have specified recent VVERs. Furthermore, Finland was described as choosing Rosatom for its next reactor in July. Rather a private Finnish consortium had proposed using a Rosatom reactor for an already approved project.
In “Researchers Aim to Level the Playing Field for Patients Awaiting New Livers,” by Dina Fine Maron [Advances], the key to maps indicating wait times for liver transplants had an error in it. The corrected graphic can be seen at ScientificAmerican.com/liver-transplants.
“Why Humans Live So Long,” by Heather Pringle, incorrectly describes the causes and effects of the heat and swelling associated with inflammation. It should have said heat and redness come from an increase in the flow of warm blood to damaged tissue and swelling results when increased vascular permeability causes blood cells and plasma to leak into the affected area.
