How does the public opinion shift in an age of polarization, social media, and easily manufactured moral shocks? How does legitimacy shift in real time? How do societies redefine what can be said, defended, and done?

I have been thinking about this for some time in the context of the shift in worldwide public opinion about the state of Israel. The shift is clear. But how exactly is it happening?

When it comes to similar changes, there are, of course, people who believe in one of the two extremes:

It is completely random or chaotic. Nobody is steering this. The world is too complex, decentralized, and unpredictable for anyone to control or drive outcomes and the narrative. Call it complexity/chaos absolutism or an anti-conspiratorial approach. People on this side tend to underestimate power, coordination, agenda-setting, and institutional influence. They can become blind to the fact that while no one controls everything, some actors clearly have vast influence and can shape what gets amplified, what gets ignored, and so on.
It is all part of a grand plan. On the opposite side of the spectrum are those who believe that small groups of people, or some specific states, or corporations (pick your poison) are controlling the narrative. This is the classic terrain of conspiracy theorists and paranoid grand-design believers. The mistake at this end is overemphasizing agency. They see coordination where there may only be convergence. They are often right that elites, states, and corporations do try to shape narratives. Their error is turning influence into omnipotence. And the mistakes are underestimating incompetence and chance, and overestimating secrecy and control.

The reality is, of course, neither. Powerful actors try to shape the narrative, yes. They sometimes succeed to a degree. But they do so within a world that is too complex to master completely, so the outcomes are always a messy mix of design, incentives, accidents, reactions, and the unexpected.

The world is neither completely chaotic nor run by puppeteers. It is, fortunately or unfortunately, messier than both.

Which brings me to the Overton Window.

The Overton Window is the idea that, at any given moment, there is a limited range of views or policies that the public considers politically acceptable, or even discussable. Ideas outside that range are treated as too extreme. Fringe. Taboo. This concept helps understand why politicians do not simply choose whatever policy they want, but usually try to operate within the boundaries of what society is ready to tolerate or support.

It is named after Joseph P. Overton, an American policy analyst, who developed the idea in the 1990s as a description of the limits that public opinion sets on political action.

Now, the Overton Window is neither fully engineered nor random. People and institutions are constantly working to move it: activists, governments, parties, media outlets, think tanks, lobby groups, NGOs, corporations, influencers, and intellectuals. They all try to change what sounds normal, respectable, or outrageous. They frame issues, choose language, repeat certain stories, elevate some voices, marginalize others, and create pressure.

But they do not control the whole process. Many players simultaneously push their agendas. Wars, scandals, economic pain, viral images, demographic change, generational turnover, technological shifts, and public fatigue can push opinion in ways no one fully plans. Think of the death of the Syrian child Alan Kurdi in 2015, the image of him going viral, and how the discourse regarding Syrian refugees changed as a result.

Now, let’s explore how the Overton Window works:

The Unthinkable Becomes Mainstream

Once you understand the concept of the Overton Window, you start seeing it everywhere. You see it in politics, media, corporate life, universities, international organizations, and even family conversations. It helps explain why some ideas are dismissed as outrageous in one decade, debated seriously in the next, and quietly turned into policy after that. It also helps explain why intelligent leaders sometimes keep defending yesterday’s consensus long after the ground has shifted under their feet.

In the classic version of the Overton Window, politicians are not free to support just anything they personally like. They operate inside a moving band of social legitimacy. Ideas inside that band feel normal, respectable, and “serious.” Ideas outside it feel fringe, extreme, or unsayable. The politicians do not usually move first. They often follow the zone of acceptability that society has already made available to them.

That is the first thing to understand: the Overton Window is not about what is right. It is about what is acceptable.

And the acceptable is not fixed.

An idea can move from unthinkable to radical, from radical to discussable, from discussable to respectable, from respectable to common sense, and from common sense to official policy. Policies once treated as outlandish can become normal; policies once treated as obvious can become unacceptable.

That is why the Overton Window matters so much to leaders. Most leaders imagine their main task is choosing between options. Very often, their real task is noticing that their options, the “menu”, so to speak, have changed.

The Overton Window step by step

I have seen the Overton Window described as if it were a secret manipulation technique. Sometimes it is presented almost like an ideological magic trick: say outrageous things often enough, and soon the public will accept them.

That is too simplistic.

The Overton Window is a descriptive model. Think of it like this. On any contentious issue, there is a spectrum of possible positions. But only some of those positions feel “normal” to the average person, a voter, the respectable editor, the cautious executive, the ministry spokesperson, or the party operative. That middle territory is the window.

The window usually shifts gradually. People hear new claims. They encounter new evidence. The emotional tone changes. Journalists use different words. Public figures stop apologizing for saying what used to require hedging. Then, one day, a sentence that would have ended a career years earlier passes with barely a notice.

The process usually follows a rough pattern. Let’s go step by step.

First, an idea exists at the margins. A few activists, scholars, dissidents, or cranks are saying it. Most people dismiss it. Institutions punish association with it. The safest response is silence.

Second, the idea becomes discussable. Perhaps not respectable just yet, but discussable. A few mainstream journalists raise the question. A few public intellectuals ask whether the taboo might be too rigid. A relevant scandal, war, financial crisis, or humanitarian disaster forces attention. Suddenly, “nobody can even talk about this” becomes “well, we should at least be allowed to debate it.” Familiar?

Third, language softens resistance. The same substance is now introduced with more cautious vocabulary. Instead of a slogan, it becomes a “concern,” a “review,” a “conversation,” a “need to reassess.” Institutions start getting in on the party.

Fourth, elite cover appears. A respected politician, judge, academic, business leader, newspaper, or international body says the once-taboo thing in a controlled and professional register. This matters enormously. Many people do not form views from scratch — they infer what is acceptable from credible messengers.

Fifth, the social risk flips. At first, you were punished for saying it. Later, you are expected to at least acknowledge it. Watch out, eventually, you may be punished for refusing to acknowledge it.

The important point is that Overton shifts are not merely intellectual. They are emotional and social. People do not just change beliefs. They change what they believe other people are allowed to believe. That second-order shift is often more decisive than the first.

Israel as an example

One of the clearest current examples is the global shift in attitudes toward Israel, especially in the context of Gaza and the wider regional wars.

For decades, in much of the West, strong criticism of Israeli state conduct existed, but within narrow bounds. You could criticize settlements, perhaps. You could criticize particular government or military actions. But in many mainstream settings, especially in politics and establishment media, sharper moral language was heavily constrained. To question the broader framework of unconditional support, to place Palestinian suffering as central rather than incidental, or to suggest that Western governments should materially distance themselves from Israel often carried a very high reputational cost.

That window has moved.

In the United States, Pew reported in April 2026 that six in ten Americans now hold an unfavorable view of Israel, up seven points from the previous year and nearly twenty points since 2022. Among Democrats and younger adults, the shift is even sharper. In Gallup’s 2025 tracking, just 46% of Americans said their sympathies lay more with Israelis, the lowest figure in twenty-five years of Gallup’s annual measurement. Western Europe looks even starker. YouGov reported in June 2025 that net favorability toward Israel had fallen to record lows in Germany, France, and Denmark, and to the lowest or joint-lowest levels in Italy and Spain.

Once opinion moves, policy language often follows. What might come next is the possibility of curbing arms exports and concerns about complicity — notice that these points are already being raised quite aggressively at this point.

In September 2025, the United Kingdom, Canada, Australia, France, Belgium, and Portugal recognized a Palestinian state, explicitly framing the move as born of frustration over the Gaza war and aimed at reviving a two-state solution. Interestingly, the shift materialized equally on the left — Spain’s progressive government has become one of the most outspoken critics of Israeli military action — and on the right — Italy’s Giorgia Meloni suspended a defense cooperation deal with Israel.

Of course, it does not necessarily mean that every society now agrees on Israel, or that all criticism is wise or fair. It means the parameters of mainstream speech and action have changed. Positions that were once confined to activists, dissident academics, or marginal parties are now being voiced by prime ministers, politicians, and institutions that once avoided such language.

That is an Overton shift.

Why did the window move in this specific case? Several things.

First, there was accumulation. The Gaza war did not happen in a vacuum. The public had already been exposed for decades to debates about settlements, occupation, asymmetry, blockade, human rights, the need for the Palestinian state, and the failures of the diplomatic process.
Second, there was visibility. In the social media age, mass suffering is highly visible. Images, testimony, and documentation travel faster than official narratives. The algorithms facilitate that — you watch one video about the subject, your feed gets flooded with ten more. This makes the window shift. And whatever one thinks of the quality of online discourse, it has dramatically lowered the gatekeeping power of traditional institutions.
Third, there was generational change. Younger generations in many Western countries tend to read the conflict through a different moral vocabulary: the starting point is no longer the Holocaust, but human rights, civilian protection, double standards, and universal law.
Fourth, there was elite drift. Once mainstream politicians, media outlets, and public institutions began using sharper criticism, social permission widened. The window shifted further. People who already had private doubts now felt comfortable voicing them.
Fifth, there was contradiction fatigue. One of the strongest drivers of Overton shifts is not persuasion in the abstract, but visible hypocrisy. When governments proclaim rules-based order in one context (Russia-Ukraine) and appear selective in another (Israel-Palestine), they help create the very backlash they may later struggle with.

So, it is not that everyone suddenly changed ideology. It is more that the old language no longer feels credible enough to describe the reality.

Criticisms of the Overton Window

To be clear, the Overton Window is useful, but it should not be worshipped.

For one, the framework is too linear. Real life and politics are messy. People do not move along a neat spectrum from extreme to mainstream. They jump, lurch, panic, polarize, and sometimes radicalize fast.

The Overton Window also overstates the existence of a single moderate center. I don’t think there is a coherent center in most societies. The concept of the Overton Window may make you believe there is one, and thus miss the ideological diversity. In reality, there may be several overlapping windows at once — one for media, one for younger voters, one for politicians, one for diplomats, one for corporate boards. What is unsayable in one room may be normal in another.

Another problem is the very way digital platforms work. What they do is create a fragmentation with multiple bubbles, each with its own (often ideological) Overton Window. To simplify, you now have very different Overton Windows on the right and on the left. But in reality, there are many more overlapping windows.

Also, some political strategists have become adept at manipulating public opinions by using social media — in the USA, Steven Bannon, for example, argued that to win, one must “flood the zone with shit” to disorient the public and media. As the informational landscape gets overwhelmed with a torrent of content, it can push the boundaries of acceptable speech through sheer exhaustion and volume. Think Gish Gallop, but at a massive scale.

Overreliance on the Overton Window may also demotivate us from taking action for what is right. Expediency and convenience are not everything. Something can sit outside the window and still be correct. History is full of morally serious positions that were once stigmatized — think of abolition or civil rights. The fact that an idea is currently “outside the window” tells you little about its moral worth. So, if a politician says something like — “I agree with you morally, but the window is not there yet”, it can be prudence, yes, but it can also be plain cowardice.

Finally, when you focus too much on the Overton Window, it may seem like public opinion alone determines politics. It does not. Institutions, donors, bureaucracies, party structures, media ecosystems, geopolitical interests, legal constraints, and finally, individuals all matter.

Takeaways for Leaders

So what should leaders do with all this?

First, understand that the window is a live variable, not a background condition. Too many leaders treat legitimacy as if it were stable. It is not. Awareness of the shifting nature of the Overton Window is the start.
Second, do not confuse institutional consensus with public consensus. Institutions are often slower. It seems that the public mood moves before ministries, boards, international bodies, or party leaderships do, especially during crises. A leader who listens only upward will detect the shift too late.
Third, watch language before policy. The window often moves in vocabulary first. Which words are newly common? Which moral frames are gaining legitimacy? When previously taboo descriptions begin appearing in mainstream reporting, parliamentary debate, or executive language, that is usually an early signal.
Fourth, there is rarely one window. There are segments. A 25-year-old staff member, a 55-year-old donor, and a government counterpart may be inhabiting very different moral universes. Good leaders track those differences.
Fifth, do not wait for unanimity. The window never shifts with everyone on board. Leadership often means recognizing that a former fringe concern has become a mainstream moral fact before all your peers admit it.

A bonus point — don’t get too cynical. :)

Next, as a leader, you should, of course, focus on specific action:

For starters, build better sensing mechanisms. Polling matters. Social listening matters. Field reporting matters. Conversations with younger staff matter.
Next, audit your language. Are you using phrases that once sounded prudent but now sound evasive? Are you hiding behind abstractions when the public expects moral clarity? Are you struggling to understand the new lingo?
Separate principle from posture. Do not chase every shift in rhetoric. Do revisit whether your public stance still reflects your stated values. If your principles are universal, they must survive changes in convenience and alliance.
Keep an eye on what’s next. If the window moves another twenty percent in six months, how will your position look? You can’t afford to look morally asleep after the rest of the world has moved on.
Finally, you need to create room for internal dissent before external reality forces it. Organizations that punish honest discomfort become blind. The people who detect Overton shifts earliest are often younger staff, or those in the “frontlines”, subject specialists, and those closest to the human consequences of policy. Ignore them, and you lose legitimacy quickly.

Above all, leaders need humility. They should, of course, assume public opinion can be shaped, but never assume they can fully command it.

The Overton Window is not destiny. It is not a moral compass. It is not a substitute for judgment. It is only a way of naming a stubborn political reality: societies decide, constantly and often invisibly, what can be said, what can be defended, and what can be done.

The danger for leaders is obvious. If you are always trapped inside the current window, you become a prisoner of convention. But if you ignore the window entirely, you may become irrelevant.

The skill and the art is to do both things at once: understand the limits of the present, and help move these limits when conscience requires it.

If you are not careful, yesterday’s common sense can become today’s embarrassment really quickly.

So, next time you are watching the news or trying to make sense of a political debate, pay attention not only to who is winning the argument, but to how the boundaries of the argument itself are shifting. Because that is often where the real change begins.
