Q & A
ما هو الدور الذي يمكن أن تلعبه المحاكاة الحاسوبية في الحفاظ على الديمقراطية؟
-المحاكاة الحاسوبية يمكن أن تساعد في استكشاف العديد من الاحتمالات والتنبؤ بالسيناريوهات السياسية، مما يساعد في تفادي الانهيار الديمقراطي والتوترات السياسية من خلال تحليل البيانات المعقدة وتقديم حلول قبل حدوث الأزمات.
كيف يقارن المتحدث بين النشاط العصبي للدماغ والسلوك السياسي في الديمقراطية؟
-المتحدث يشبه تزامن النشاط العصبي الذي يمكن أن يؤدي إلى نوبات صرع مع تزامن السلوك السياسي للأفراد، حيث يمكن أن يؤدي ذلك إلى انهيار سياسي أو اضطرابات سياسية إذا تصرف الناس بشكل جماعي موحد دون تنوع في الآراء.
ما هو تأثير القطبية الحزبية على الديمقراطية وفقًا للمتحدث؟
-القطبية الحزبية تؤدي إلى تكدس الناخبين والسياسيين في معسكرين كبيرين دون تقاطع بينهم، مما يقلل من التنوع في الآراء السياسية ويزيد من خطر انهيار النظام الديمقراطي بسبب التزامن في التفكير والسلوك.
لماذا لا يعتبر تشكيل حزب ثالث حلاً فعالاً للقطبية الحزبية؟
-تشكيل حزب ثالث قد يكون غير فعّال لأنه يمكن أن يؤدي إلى تقسيم الأصوات بشكل يمنح الأفضلية للحزب الآخر. هذا يسمى 'تأثير المفسد' حيث يساهم الحزب الثالث في خسارة الحزب الأقرب له في الأفكار.
كيف يمكن أن يساعد إعادة رسم الحدود الانتخابية في تحسين الديمقراطية؟
-إعادة رسم الحدود الانتخابية يمكن أن يساعد في تقليل التحيزات السياسية التي تنتج عن التلاعب بالحدود (الجيري مانديرينغ) من خلال استخدام التحليل الإحصائي لاكتشاف الخطط غير العادلة ومنعها.
ما هو دور التصويت التفضيلي (الاختيار المرتب) في تحسين النظام الديمقراطي؟
-التصويت التفضيلي يساعد على تقليل تأثير القطبية الحزبية عن طريق تمكين الناخبين من ترتيب مرشحيهم وفقًا لتفضيلاتهم. إذا فشل مرشحهم الأول، يُعاد توزيع أصواتهم بناءً على اختياراتهم التالية، مما يعزز التمثيل الأكثر عدلاً.
ما هي بعض الإصلاحات الأخرى التي تم اقتراحها لتحسين الديمقراطية؟
-تشمل الإصلاحات المقترحة إلغاء المجمع الانتخابي، اعتماد نظام التصويت بالموافقة، وإصلاح تمويل الحملات الانتخابية. هذه الإصلاحات تهدف إلى تعزيز التمثيل والاستجابة للناخبين.
كيف يمكن للمحاكاة أن تساعد في تقييم الإصلاحات الديمقراطية؟
-المحاكاة يمكن أن تحاكي نتائج الإصلاحات المختلفة وتساعد في توقع تأثيرها على المدى الطويل. هذا يساعد على اتخاذ قرارات أفضل حول أي الإصلاحات تكون الأكثر فعالية وأيها يجب تنفيذها أولاً.
لماذا يجب أن تكون الإصلاحات مرنة وتتكيف مع الخصائص المحلية؟
-كل ولاية أو مدينة لها ظروفها الخاصة، لذا فإن الحلول التي قد تعمل في مكان واحد قد لا تكون مناسبة لمكان آخر. المرونة تتيح إيجاد حلول تتناسب مع احتياجات وظروف كل منطقة.
ما هو الاقتباس الذي استخدمه المتحدث من الرئيس السابق تيودور روزفلت وما علاقته بالديمقراطية؟
-الاقتباس من تيودور روزفلت يقول إن الديمقراطية هي 'تجربة وطنية حيث يجب أن تنتهي القواعد بتمثيلنا جميعًا'. المتحدث يستشهد بهذا الاقتباس للتأكيد على أن الديمقراطية تتطلب نظامًا تمثيليًا يشمل الجميع، ويمكن للرياضيات أن تساعد في تحقيق هذا الهدف.

🤖 The Role of Simulations in Preserving Democracy
The speaker introduces the prevalence of computer simulations and how they assist in everyday tasks, like navigation or weather prediction. They argue that simulations could play a vital role in safeguarding democracy, especially during times of rapid technological, demographic, and climate change. The speaker, a computational neuroscientist, draws an analogy between neural synchrony and political unrest, explaining how group actions can destabilize societies. Simulations and mathematical analysis can help prevent such events and strengthen democratic systems by ensuring representation, responsiveness, and deliberation.
📊 The Third Party Dilemma and the Spoiler Effect
The speaker discusses potential solutions to the current polarized political system. They explore the idea of forming a third party but warn that it could backfire. Using simulations, they show how introducing a third party could divide the vote and inadvertently benefit the opposing major party due to the 'spoiler effect.' The simulation illustrates how the third party's presence can weaken the chances of the party closest to its views, rather than fostering a more balanced political landscape. Redistricting is suggested as another, more effective reform strategy.
🔄 Redistricting and Ranked-Choice Voting: A Path to Reform
The speaker delves into redistricting as a reform measure and explains how gerrymandering undermines fair representation by drawing biased electoral district lines. With the help of statistical analysis, courts can identify outlier plans and intervene. While redistricting can help, the speaker emphasizes that polarization remains widespread, requiring further reforms. They highlight the effectiveness of ranked-choice voting, which allows voters to rank candidates and redistributes votes from eliminated candidates. This system promotes more inclusive elections and encourages candidates to appeal to a broader base, rather than just party loyalists.
🗳️ Exploring Other Reforms and the Power of Simulations
The speaker touches on additional reform ideas, such as eliminating the Electoral College, approval voting, and campaign finance reform. They stress the importance of prioritizing these changes and using simulations to predict long-term outcomes. Simulations provide a unique ability to evaluate the effectiveness of reforms over time, ensuring tailored solutions for different regions. The speaker acknowledges that while math alone can't solve these problems, it can be a crucial tool in guiding effective reforms. They end by encouraging scientists to contribute to these efforts and quoting Theodore Roosevelt on democracy as a national experiment.

Highlights
Simulations are widely used in everyday life, such as for weather reports and navigation.
Computer simulations can be applied to preserve democracy during times of technological, demographic, and climate change.
The speaker, a computational neuroscientist, draws parallels between brain activity and political behavior to explain societal unrest.
Neuronal synchrony leading to seizures is compared to societal behavior, where collective unison can lead to political collapse.
Mathematical analysis can explain and potentially prevent political instability and the collapse of democracy.
The paradox of modern democracy is that despite an increase in independent voters, polarization remains high.
The simulation illustrates how voters are distributed along a single left-right political spectrum, but many independents are hidden in a third dimension.
One-dimensional dynamics, like stampeding animals, can lead to political stampedes and the election of extreme leaders.
Introducing a third-party candidate without other reforms can backfire, causing a spoiler effect that benefits the opposing party.
Redistricting and combating gerrymandering are key strategies to improve representation and reduce polarization.
Ranked-choice voting, as seen in Alaska, changes the political landscape by encouraging candidates to appeal to a broader voter base.
Top-four primaries, combined with ranked-choice voting, can lead to more competitive elections and less polarization.
Simulations can help analyze the long-term outcomes of electoral reforms to ensure they work for various states and local contexts.
Some states have outlawed ranked-choice voting, highlighting the need for flexible solutions tailored to different regions.
Math and simulations act as a GPS for navigating democratic reforms, helping to preserve democracy by identifying the best paths forward.
Transcripts
Computer simulations are everywhere.
If you navigated here today or you looked at a weather report,
then you used simulations.
A simulation can game through thousands or even millions of possibilities.
What if computer simulations could help us out
of one of the most pressing problems of our time:
a rickety democracy, here in the United States
or around the world?
I'm here to argue today
that simulations can help us preserve democracy in a time of crisis,
in a time of rapid change,
both technological and demographic and indeed climate change,
and tension, again in the US and around the world.
I'm a computational neuroscientist,
and I'm used to handling complex data.
My students and I study the brain, a highly complex object.
We take data and we make it simpler in order to understand it.
We also build models to help understand how a brain might react.
And this kind of understanding, I argue,
is useful in understanding democracy itself.
Imagine neurons, which I do a fair bit.
When neurons fire together in synchrony,
and they fire impulses together,
that can lead to a seizure.
Now imagine people doing something together.
When people start believing something in unison or acting in unison,
that can lead to political collapse, and it can lead to unrest,
and it can even lead to insurrection.
Computation and mathematical analysis
can help explain strange phenomena like this,
which are unfamiliar to most of us in our lifetimes.
They can not only help explain
but they can also help prevent such events from happening
and maybe even help make repairs to democracy.
And finally, and this is important,
avoid accidentally causing a problem or making things worse.
I would argue, too,
that democracy ought to have several fundamental functions.
It should be representative of all of us.
It should be responsive to us.
If we change our minds, we should be able to get rid of the people
who we think have not been doing a good job.
And finally, democracy should be deliberative.
We should elect people who represent us,
who deliberate with one another and help solve our problems.
But there's a paradox in our democracy as it stands today.
And let me explain to you exactly how that paradox might cause a problem.
If you look at recent surveys,
many of us are dissatisfied with politics.
There are more independents
than either Democrats or Republicans.
That started two decades ago.
Over the last few years,
there are now nearly half of voters in the United States
who call themselves independents.
That's more than Democrats and Republicans combined.
But yet we're also polarized.
Those independents also have highly reliable voting habits,
voting with either major political party most of the time.
So how can that be?
Let me show you a simple simulation
that illustrates how both of those things can be true:
independents who are disaffected and yet partisan polarization.
And this helps to illustrate
how there could be a danger to our system under current conditions.
In this simulation,
look at this axis from left to right.
This is an axis that's meant to represent liberals and conservatives
from left to right.
And you can see here voters,
or if you can imagine, politicians, piled up in two great mountains.
And these two great mountains are separated from each other.
Very little overlap in issues or in cultural stances.
There's something different about these two mountains.
But now take a closer look.
This is one dimension that I've shown you,
a single dimension from left to right.
But look, here's a third mountain hidden.
And that's because there's more dimensionality to voters
than just the single axis
that we've gotten used to in the last few years.
This third mountain of voters, in fact, has different stances,
but yet they're forced to choose.
They have to pick whichever major mountain is next to them,
and whichever mountain is closer, they pick.
And that's why we're loyal.
And when we're forced to choose between these two major mountains,
we're all forced to act as if we're on that single dimension.
Mathematical analysis has shown that one-dimensional dynamics,
as you go along a single dimension, can lead to instability.
And that's important.
To get into the math a little bit, imagine animals.
If animals all start moving in one direction,
then that puts them at risk of getting into a stampede.
Now imagine people.
If we all start doing the same thing,
if we all start behaving in unison, if enough of us do that,
that can cause a political stampede.
And a political stampede can lead to the election of extreme leaders,
and it can lead to a collapse of democracy and maybe the loss of democracy
and future elections.
Can we prevent this?
Well, I should say that reformers have come up with lots of ideas.
And if you've been paying attention to this space,
you've heard about some of these ideas.
But the problem is that we do not have the luxury of time.
It's an unstable time.
And I would say that it would be a good idea for us
to make some of these repairs in the next few years.
And we have to get it right maybe the first time.
Simulation can help.
Like navigation on a smartphone,
computation can help us identify paths that can move us forward reliably
and without making too many missteps.
Now I’ve told you about independents.
Now I want to tell you about some of the solutions.
Now you might imagine that a good idea in such polarized circumstances
is to form a third party.
Sounds good, right?
But in fact, if we do that before attempting other reforms,
that can backfire.
And I'd like to show you a simulation that proves the point.
Here's a simulation based on analysis
that my collaborators and I have undertaken.
This is now based on results from analyzing hundreds of elections.
And we found that voters indeed do act
as if they are piled up into two great mountains.
In this case, I’ve shown the blues on the left
and the reds on the right.
And in this simulation, they vote under the normal rule
that we’ve become used to, which is called first-past-the-post.
And in this simulation I've set up conditions
so that out of 10,000 simulations, the blues win half the time, 5,000 times,
and the reds win half the time, 5,000 times.
And in the simulation, the fraction of the vote
that they need in order to win is about 50 percent.
These are the conditions that we're used to in a two-party system.
Imagine if we suddenly run a third-party candidate
and we put that third-party candidate in the middle.
The third-party candidate is here in the middle,
and I've set up the simulation to be a little bit closer
to one of those peaks than the other,
because that third party is more sympathetic to those views.
However, there's something a little bit funny here,
which is that now that blue party
still needs 50 percent of the vote to win.
But now, because the third party has divided the vote,
now the reds only need 46 percent of the vote to win.
And now we have a situation in which out of 10,000 simulations,
the blues win now only 2,000 times, the reds win 8,000 times,
and the third party doesn’t win at all.
And so this is counterproductive, right?
This is what we call a spoiler effect, where paradoxically,
the third party has spoiled the chances of the party that is closer to them,
which is presumably the opposite of what they were trying to accomplish.
Now there are other solutions that it turns out are more likely to work.
And one of them is redistricting.
In the United States,
we're mostly represented in single-member districts,
and so we have a particular legislator who represents us.
In recent years, there's been a move to stem this.
You may have heard the word gerrymandering.
Gerrymandering is the artful drawing of lines
to disadvantage one candidate or a group,
could be a racial group or a whole political party,
and to eliminate competition.
Computation can help identify such a plan.
By doing statistical analysis of the universe of possible plans,
it’s possible to show that a particular plan is an outlier.
And when there’s an outlier, then a court can intervene.
When the court intervenes, it can dictate the drawing of a new plan.
Computation can also help voters.
Voters who vote to change the system, to change the rules,
to establish an independent commission,
can also take the power away from legislators,
and they again will need computation.
However, this solution, as attractive as it is, is not enough.
And that's because those two mountains which I showed you are everywhere.
And no matter how much we redraw the lines,
there's polarization across the nation.
And so the question is, OK, what else do we need to do?
There's something else that's necessary.
The next step is to change the rules of the game itself.
Alaska voters in the last few years have done exactly that.
They voted to do away with partisan primaries.
What they've done is remove the primaries
and replace them with an all-party primary.
Everybody runs in one single primary.
The top four advance to the general election.
Because there are four candidates,
they then have to be elected under a ranked-choice rule.
Ranked choice is one where you list your first choice, second choice,
third choice, fourth choice.
If your first choice doesn't cut the mustard,
then they drop out, and your vote is reassigned.
The consequence of this is that Democrats and Republicans
still have a chance to advance, and they do, to the general election.
But it changes the incentives.
They have to play not to their party faithful
but instead they play to all voters.
It changes tactics.
They try to win over each other's supporters,
and it changes attitudes.
And just to give you an example,
here's a selfie that's taken by three congressional candidates,
one Democrat and two Republicans.
And here they are chumming it up, taking a selfie together.
And I can tell you that at least one of these candidates
is not in the habit of chumming around with a member of the other party.
(Laughter)
So this is one way that, in fact, a new change of rules can help.
And in fact, we've done simulations that show that this rule,
which is called top four primary, works with redistricting reform,
the other one I showed you.
Put together, they can, in fact,
double the number of competitive districts.
So there's even a case in which there's synergy that's possible.
Now I’ve given you a few ideas,
but there are actually many ideas for reform and you may know them:
eliminating the Electoral College,
approval voting, campaign finance reform.
The question is how to choose
and how to figure out which ones to do first
and with the most urgency.
And simulations can again help.
Simulations can game out outcomes.
Representation, responsiveness, deliberation.
And simulations can do something
that enacting a reform cannot do easily,
which is game out long-term outcomes.
What’s going to happen 10 years from now?
And that's important.
Furthermore, every state is different, cities are different.
The same solution is not going to work in every place.
And so it's important to be flexible
and to look for the solution that works best.
Somewhat shockingly, some states have even outlawed ranked-choice voting,
and so one would have to come up with another solution for those places.
Now let me be realistic.
Math is not enough.
But math can be assistive,
and it can help speed the process for people who want to change the system.
In other words, math and computation can act as a GPS
to rescue our lost democracy.
Now the way you can help is by advocating for reforms
through voter initiatives in states that have that.
You can advocate for local reform in your city or town.
And if you're a scientist, I really want your help.
If you're a scientist, I want you to come
and get to work understanding these things
in your city, in your town, in your state and in your nation.
As it turns out, some of these reforms, such as ranked-choice voting,
have been run in hundreds of elections across America.
And that means there are experiments being done right now in real time.
I want to end with a quote from a former president, Theodore Roosevelt,
who was not a scientist, but in fact was very interested in this.
And he called democracy an experiment.
He said, "Democracy is this national experiment
in which it's essential for the rules to end up representing all of us."
It's my hope that math can help get us there
and build a better future for all of us.
Thank you.
(Applause)
