BRAIN Initiative – on MSNBC

May 2nd, 2013, 12:33pm by Sam Wang


I’m currently in heavy neuroscience mode. Here’s one example: the unveiling of the BRAIN Initiative, an NIH/NSF/DARPA/private research initiative announced by President Obama in April. It focuses on new technologies to map brain connectivity and function. Whether there will be new money isn’t clear, but it does highlight some very exciting areas in modern neuroscience.

Dig beneath the public rollout, and there’s a roster of scientific advisors that provides a clue as to where it’s headed. Listed are some of the best leaders and technology developers in understanding circuit-level brain function. It’s a promising start. I predict that next we’ll see new Requests for Applications (RFAs) issued by NIH and NSF. That would be a prosaic route, but without a single central goal…let a hundred flowers bloom!

Finally…here I am on Melissa Harris-Perry’s program to talk about the BRAIN Initiative. NBC has split it into Part 1 (BRAIN Initiative), Part 2 (implications for Alzheimer’s), and Part 3 (what brain scans do — and don’t — reveal in individuals). Watch me spar with the pundits.

Review of The Signal and the Noise

February 14th, 2013, 8:22pm by Sam Wang


In Science magazine, Ben Campbell and I have a review of Nate Silver’s book, The Signal and the Noise. Briefly…it was good for people who don’t know any math or science, and was best when he recounted his own exploits in poker. But there were some flaws, for instance on the use of statistics in science. And on climate change…let’s leave that alone.

Slaying the gerrymander

February 3rd, 2013, 8:21am by Sam Wang


(Welcome, New York Times readers!)

Thanks to commenters on this topic. Your feedback has shaped my thinking on this subject. I recall being skeptical that redistricting could have a major effect. As it turns out, the effects of partisan redistricting helped Republicans far more than I expected.

One reason for my skepticism is that the the effect was clustered tightly in a handful of swing states. My pre-election calculations did not look for state-specific effects (though they were still fairly accurate); it was only after the election that I developed the right statistical tools. All extreme partisan gerrymanders were done in states with GOP-controlled redistricting. Furthermore, they are swing states, putting them on a knife edge and making them places where gerrymandering could help eke out extra wins.

First, some links to previous essays. Then some answers to your questions. [Read more →]

Reince’s plan, Carrico’s folly

January 25th, 2013, 8:59am by Sam Wang


Here’s an article by Steve Coll on gerrymandering in the New Yorker. The subject is not dying away – quite the opposite.

Some of you thought that the effect I have detected – antidemocratic outcomes in PA, OH, MI, NC, VA, FL, and IN in 2012…

…was somehow peculiar to their population patterns. I’ve been doing analysis showing that the effect wasn’t there in 2010, just two years earlier. I could polish that up to show later.

However, now it’s unnecessary. Republicans have basically owned up in a strategy memo:

As the 2010 Census approached, the RSLC began planning for the subsequent election cycle, formulating a strategy to keep or win Republican control of state legislatures with the largest impact on congressional redistricting as a result of reapportionment. That effort, the REDistricting MAjority Project (REDMAP), focused critical resources on legislative chambers in states projected to gain or lose congressional seats in 2011 based on Census data.

Controlling the redistricting process in these states would have the greatest impact on determining how both state legislative and congressional district boundaries would be drawn. Drawing new district lines in states with the most redistricting activity presented the opportunity to solidify conservative policymaking at the state level and maintain a Republican stronghold in the U.S. House of Representatives for the next decade.

To fund the initiative, the RSLC raised more than $30 million in 2009-2010, and invested $18 million after Labor Day 2010 alone. Specifically, the RSLC…

Spent nearly $1 million in Pennsylvania House races, targeting and winning three of the toughest races in the state.
Spent nearly $1 million in Ohio House races, targeting six seats, five of which were won by Republicans. Notably, President Obama carried five of these six legislative districts in 2008.
Spent $1 million in Michigan working with the Michigan House Republican Campaign Committee and Michigan Republican Party to pick up 20 seats.
Spent $1.1 million in Wisconsin to take control of the Senate and Assembly.

So there you have it. Read the whole thing – it’s illuminating.

This week there’s a new layer: Virgnia state Senator Charles Carrico is sponsoring a plan to allocate his state’s electoral votes by district. This would lead to a mismatch between the statewide popular vote and EV outcomes – just as it has for their Congressional delegation. For instance, the popular vote there was Obama 51%, Romney 48%. But under the new plan, the electoral outcome would be Romney 9 EV, Obama 4 EV.

What’s interesting about this scheme is that it basically pits the interests of the national Republican party against the interests of Virginia voters. Virginia is both a large state and a swing state, and was therefore of great interest to the Obama and Romney campaigns.

Last year, individual voters in Virginia had a lot of influence in the national election. Look in The Power Of Your Vote in the right sidebar. You will see that they were more influential than voters in all but a handful of states.

Such a mechanism is not inherently antidemocratic: in our current system, overall national opinion is measured by Electoral College rules that are largely uniform – and end up mostly in line with the popular vote.

However, Carrico’s rule change would have two effects. One is the outcome desired by RNC chair Reince Priebus: control over electoral vote allocation by the redistricting process. In this scenario, the flaws of the Electoral College are magnified, not reduced.

This leads to the second effect: only one or two districts in Virginia would be up for grabs. Virginia’s power would therefore be reduced to that of South Dakota. No offense to South Dakota, but I don’t think Virginia voters will like that. However annoying it is to live in a swing state in an election year, it’s better than being ignored.

One analysis of this type of rules change misses the point entirely, pointing out that changing all states to Nebraska/Maine allocation rules (1 EV for each district, plus 2 EV for the state’s vote winner) would have produced a Romney win in the last election, 273-265. However, note that the push for change is only occurring in swing states – the same ones where gerrymandering has succeeded to such new extremes. In this respect, a theme has emerged that dates back to Bush v. Gore in 2000, and has continued with voter-ID laws: the goal is to win near-tied situations. It’s an impressive long-term strategy.

Environmental lead (Pb) and crime

January 4th, 2013, 6:30pm by Sam Wang


At Mother Jones, Kevin Drum has an in-depth article on the hypothesis that environmental lead  is a likely root cause of the increase in crime a generation ago. Even more importantly, removal of lead from gasoline may be responsible for the decrease in crime in the last few decades. Last night, Kevin and I discussed these ideas with Jay Ackroyd on Virtually Speaking.

Support for the environmental-lead/crime association has been building for some time, as described for example in these articles by Rick Nevin and David Carpenter. Two key elements are there: (1) historical epidemiological data from many countries, and (2) a plausible biological mechanism (PDF): effects of lead on the developing brain, especially the prefrontal cortex, and on IQ.

Gerrymanders, Part 2: How many voters were disenfranchised?

January 2nd, 2013, 2:32pm by Sam Wang


(Welcome, redditors! And for the hardcore nerds…)

Redistricting is a large and sometimes arcane subject. Take a look at the comments section for the last post. Some of you are quite knowledgeable on the subject. Others are new to it. Before I continue, I’ll lay out some basics, and explain what it is about this problem that interests me. [Read more →]

Gerrymanders, Part 1: Busting the both-sides-do-it myth

December 30th, 2012, 12:29pm by Sam Wang


Left: Eric Carle's caterpillar. Right: NC 12th DistrictThe Washington Post Second Annual Wonky Awards are out. Wow, there I am for Best Election Modeler. Thank you!

(Mental note: If I ever meet the Worst Modeler recipient, Dick Morris, remember to avoid shaking hands. The whole particle-antiparticle thing. We’d annihilate or get stuck together. Either outcome is bad.)

>>>

As current negotiations over the [fiscal cliff] / [austerity bomb] make clear, rank-and-file Republicans in the House of Representatives are not receptive to the policy implications  of November’s election. As correctly pointed out by Nate Silver,  members of Congress are increasingly insulated by the increasing polarization of their districts. Ever-larger victory margins reflect ever-safer re-election races.

However, Silver has also restated a common belief. He states that partisan gerrymandering is a symmetric problem, i.e. both Democrats and Republicans do it. Although both sides are potentially motivated, only one side has taken redistricting to extremes. Recent changes in partisan gerrymandering constitute one of the major crises facing our system of government (link to Mann/Ornstein book, a fellow Wonky winner).

Today I give an analysis that pinpoints some exceptional – and asymmetric – aspects of this year’s Congressional redistricting. I base this on criteria I have developed for identifying when a political party has been disenfranchised in a particular state. I conclude that the antidemocratic balance of power in the incoming Congress is driven by just a handful of states.

In this and coming posts I will address the following topics:

  • Part 1: Developing a “tell” for partisan gerrymandering, and evidence for partisan asymmetry.
  • Part 2: An estimate of how many people have been disenfranchised.
  • Part 2/3: Steps that would re-enfranchise voters by 2020 or sooner.

In search of the nerd/poet gene

December 26th, 2012, 11:00pm by Sam Wang


Today, I ask for your help with my laboratory research. It will only take a few minutes.

The concept of a “physics gene” or “poetry gene” might not be a joke. Intellectual predispositions are likely to be driven in part by genes – including those that drive autism, mood disorders, and substance abuse.

My students and I are building a tool to measure intellectual phenotypes. To participate, take our brief survey. Continue here… [Read more →]
