@billmaher Love you Bill

People say the left and the right can’t agree on anything these days. But there is this one thing:

melaniephillips.substack.com/p/an-unholy-ac… The Pope said his aim was to build “bridges between the Christian world and the Muslim world”. But building bridges between sheep and wolves merely provides the wolves with an easier way to tear the sheep to pieces. His condemnation of the war against Iran rather than the Iranian regime itself serves to line up the Vatican with the debauched amorality of countries such as Britain, France, Italy and Spain, which have taken a similar position.

Well that ends the debate on deaths in Gaza. Hamas itself is admitting that 80% of casualties were combatants. There was never a genocide. You have been lied to and manipulated.

@yudapearl It’s very saddening, the point then is what to do next, how can all the crazy world be put back on decent tracks

So befitting. I've just spent 5 minutes looking straight at Ariel's face below, while talking to myself about humanity and where it's going. Try it.

Today, the Islamic Republic hanged multiple Iranian civilians, some of whom were just teenagers. Amnesty International? Silent. The UN? Silent. Human Rights Council? Silent. The Red Cross? Silent.

Woke progressive madness got completely destroyed by Melanie Philips. This may be deemed offensive to members of the Woke-Jihadist alliance. So please share this! twitter.com/CherylWroteIt/…

Believe them.

@yudapearl @sbc111 @TDataScience How true

I find it difficult to connect with this book. It is not a secret that I have been critical of the "potential outcomes" framework of causation . This framework instructs researchers to accept certain assumptions stated in an opaque language, which prevents them from judging the plausibility of those assumptions. A book devoted entirely to this framework reinforces the fallacy—prevalent among some economists—that researchers can draw useful conclusions from assumptions they do not understand. @eliasbareinboim @analisereal @VC31415 @guido_imbens

As a non Jew, I think it is very easy to miss the sheer toxicity of Antisemitism out there Just make mildly pro Jewish comments and you'll suddenly get it directed at you too I am proud to stand with Jews. This hate is evil and must be fought.

@eliasbareinboim @yudapearl Very nice observation Elias, about the many to one map between causal structures and transitions … I think this is essentially all one needs to know to appreciate the need of actual causal models. Thanks for making the point.

Action conditioned models estimate transition kernels. But the same transition statistics can arise from different causal structures that imply different consequences under new policies. This means policy evaluation becomes a causal identification problem, not merely a prediction problem. This observation is closely related to the distinction emphasized by @yudapearl between interventions and the underlying mechanisms that generate them. I discussed this in an ICML tutorial a few years ago, link: crl.causalai.net. Part III of my forthcoming book Causal Artificial Intelligence discusses this in detail , including examples where identical MDP transitions correspond to different causal environments (see Fig. 8.4, p. 544): causalai-book.net Reinforcement learning and representation learning are important pieces of the puzzle, but causal structure must also be treated as a first-class component of intelligent systems.

@yudapearl @ylecun How to tell a scientist (JP) from someone else

Models specified by "action conditioned" knowledge, as in classical control theory, are surely "causal" but are not "world models" in the causal sense. The former requires specifying the effect of every action or combination of actions; the latter permits the derivation of such effects from a compact description of (causal relationships in) the world, not of actions. To appreciate the difference, see "Does Obesity Shorten Life? Or is it the Soda? ucla.in/2EpxcNU Another way to appreciate the difference is to consider a city road-map, as an example of world model, and contrast it with GPS instructions, "Go right, left or straight", which contain the same information about approaching the destination, but not about handling unforeseen road blocks.

We are notified of a unique event in the history of AI-investment: Yann LeCun's AMI Labs launches with $1.03 Billion to build AI "that understand the world". frenchtechjournal.com/yann-lecuns-am… Comment: There is no "understanding the world" without causal modeling of the world and, strangely, LeCun has not shown any interest in causal modeling in the past. I do not know what to make of it except to repeat my comments when the WSJ article came out: archive.is/2025.11.16-234…. I said: "evidently, LeCun has just discovered "world models", I hope to see lots of funding pouring into CI soon."

As the Prophet Mohammad (PBUH) once said: The only way to fight Zionophobs is through humor and satire; Quote them widely and mock them down to eternal ridicule --thus spake the Prophet. @zoecabina @AkaLazarus @BarbaraRKay @hahussain

@yudapearl Lots of congrats Judea!! All too well deserved!

Dear readers, I was honored with the following Award: The 2026 National Academy of Artificial Intelligence Exploration Award " For establishing the foundations of causal artificial intelligence." See: thenaai.org/index/index/ne… I hope it brings a small  sprinkle of glamour to the entire causal inference enterprise. Congratulations also go to our colleagues @tdietterich and Leslie Valiant, who are sharing this award for their pioneering works.

@yudapearl @adam_louis52328 In the same spirit: instagram.com/reel/DVdNQ2sjV… :)

The only way to fight antzionists is with satire, humor, parody, wit, and mockery—laughing them into permanent disgrace. Their narrative—a web of contradictions and bad faith—collapses the moment it meets ridicule. Judge for yourself: youtube.com/watch?v=6SJzae… @adam_louis52328 @LekhtNaya @AndrewPessin @GadSaad

@RestoringWest @yudapearl Dear Ayaan, all good but “faith”. It’s a pity you haven’t stayed on the non-theistic side, along with Sam Harris.

The Restoring the West Manifesto I spent the first part of my life living under oppression. I know what it means to be silenced, to have your freedom stolen, to watch a civilization reject the very values that make human flourishing possible. I also know what it means to be free. And I know that freedom is not inevitable — it must be defended, understood, and taught anew to every generation. The West is at risk of losing that fight. And too many people who should be leading the defense have no idea how to do so. That’s why we’re launching Restoring the West. The Crisis We Face The civilization that gave the world individual liberty, the rule of law, scientific inquiry, and human dignity is under siege — not primarily from external enemies, but from internal collapse. Many of our institutions have been captured. Too many of our universities teach students to despise their own inheritance of broad thought and discourse. Our media amplifies every grievance to leftist ideology, while ignoring threats from intolerant ideologies and forces. Our leaders lack the moral vocabulary and fortitude to defend what we’ve built. Meanwhile, illiberal ideologies — from political Islamism to postmodern identity politics — advance unchecked, demanding submission to group identity over individual conscience, censorship over free speech, and tribal loyalty over universal human rights. Classical liberals and conservatives? Too often, we’re losing. We win elections but lose the culture. We defend policies but surrender the principles. We react to provocations but fail to plant ideas that endure. We even wage wars to liberate oppressed people in other nations, yet we fail to explain—both to outsiders and to our own citizens—the moral absolutes that demand we use our power against evil, such as the death cult that served as the operating system of Iran’s Islamist regime. The West will not be restored by winning news cycles. It will be restored by winning the argument for why the West is worth preserving. Our Guiding Principles: DEFEND JUDEO-CHRISTIAN VALUES, UNAPOLOGETICALLY The features that have uniquely made our civilization a place where all can flourish are rooted in the Judeo-Christian tradition: individual liberty, equality before the law, freedom of conscience and expression, and the dignity of every human being. These values built free societies. These values are now under attack. We will defend them without apology or equivocation. FIGHT ILLIBERALISM IN ALL ITS FORMS Whether cloaked in religious orthodoxy or academic jargon, illiberalism seeks the same end: the suppression of individual freedom in service of collective control. We oppose political Islam, which seeks to impose religious law on free societies. We oppose postmodern ideologies that replace individual rights with identity hierarchies. We refuse to choose between these threats. We recognize them both as enemies of Western civilization. PLANT IDEAS THAT ENDURE This publication is not about outrage or affirmation. It's about intellectual ammunition. Every piece we publish will advance a clear argument, address serious objections, and connect to the project of civilizational renewal. We write for people who need to be persuaded, not just people who already agree. Our goal is to shape minds, change debates, and arm veterans and new generations for the work ahead. SPEAK WITH MORAL CLARITY I did not escape one form of oppression to tolerate another. I will not pretend that all cultures are equal, that all ideas are equally valid, or that we can restore the West through euphemism and evasion. Moral clarity is not extremism — it's the precondition for moral action. We will say what is true, even when the truth is uncomfortable. FIVE PILLARS, ONE MISSION Everything we publish connects to the civilizational foundations we must restore: Faith & Family - The roots of free societies Education - Where the future is won or lost Law & Liberty - Without which we are subjects, not citizens Nation & Citizenship - The framework for self-governance Media, Arts & Culture - Where values are formed or deformed These aren't talking points. These are the fronts in a war for civilization itself. SMART BREVITY, SERIOUS PURPOSE Busy people need clear arguments, not bloated essays. We respect your time by making every word count. But efficiency serves substance, not the other way around. We will never sacrifice intellectual rigor for algorithmic reach or dumb down complex arguments for easier consumption. Excellence is the standard we want restored in our civilization — it’s the standard we hold ourselves to here. Why This Matters I have seen what happens when civilizations abandon their principles. I have lived under the thuggish sandal of illiberalism. I know the price of freedom because I know what life costs without it. Too many of the institutions that once defended Western civilization have failed or been captured. The task of restoration falls to us — to those who understand what’s at stake and refuse to surrender what generations before us built and bled for. This is not pessimism. This is realism coupled with resolve. The West can be saved. But only if we’re willing to make the argument for why it deserves to be saved — and then do the work required to save it. Welcome to Restoring the West. — Ayaan Hirsi Ali
