How Social Media Are Changing Not Only Travel but Also the Way Democracies Understand the World
“The real voyage of discovery consists not in seeking new landscapes, but in having new eyes.”
— Marcel Proust
Proust’s observation is usually read as a reflection on personal growth. It is also, perhaps unintentionally, a profound insight into geopolitics.
For centuries, the most important consequence of travel was not merely crossing borders. It was the acquisition of knowledge. Every merchant, student, diplomat, scientist, tourist or migrant who crossed frontiers returned with something more valuable than photographs or souvenirs: a more nuanced understanding of people whose lives, cultures and aspirations often differed far less than political narratives suggested.
This raises a question that has grown increasingly important in the digital age.
How do democratic societies come to know the world beyond their borders?
The answer has never depended exclusively on governments, diplomats or journalists. Democracies build their understanding of international affairs from millions of individual experiences. Conversations with strangers. University exchanges. Business travel. Scientific cooperation. Tourism. Family migration. Chance encounters on trains, in cafés or at airport gates. Each interaction, however modest, contributes to the collective picture that societies develop of foreign peoples and nations.
Travel has therefore always been more than mere mobility.
It has been an institution of learning.
Today, however, that institution is undergoing a profound transformation.
The paradox of globalization
Humanity has never travelled so much.
International tourism has surpassed pre-pandemic levels, educational exchanges continue to expand, and global business mobility has become a routine feature of economic life. Never before have so many individuals crossed international borders so frequently. Yet an emerging paradox exists.
The very technologies that have made global communication effortless may also be diminishing one of travel’s most valuable functions: the chance to experience unfamiliar societies firsthand. Anyone boarding a train or waiting at an airport today encounters a familiar scene. Hundreds of people occupy the same physical space yet remain immersed in personalised digital environments. Headphones replace conversation. Personalised news feeds replace observation. Waiting becomes scrolling.
This is not merely a matter of changing social habits. It may signal a deeper transformation in how citizens acquire knowledge of the world.
For generations, travel fostered what psychologists would describe as meaningful contact with unfamiliar people. A conversation with a taxi driver in Shanghai, dinner with a family in Naples, a debate between students in Berlin, or a chance encounter during a delayed flight often provided insights that no newspaper article or television report could fully capture.
Such encounters rarely transformed political beliefs overnight.
Their importance lay elsewhere.
They complicated stereotypes.
They introduced ambiguity.
They reminded travellers that societies are invariably more complex than the simplified images through which they are often portrayed.
From experience to mediation
The digital revolution has not eliminated travel.
It has altered its connection with experience.
The contemporary traveller remains permanently connected—not primarily to the surrounding environment, but to a continuous stream of algorithmically curated information. While moving physically through foreign societies, many individuals remain cognitively embedded in familiar digital ecosystems that follow them wherever they go.
This distinction matters.
The issue is not whether social media provides information. They undoubtedly do. They have expanded access to international news, enabled direct communication across continents, and given voice to individuals previously excluded from global conversations.
The question is different. What happens when mediated representations progressively replace direct observation as the primary means by which citizens understand foreign societies?
This question extends far beyond tourism.
It concerns the epistemic foundations of democracy.
The new geography
Every democracy ultimately formulates its foreign policy through public consent.
Governments negotiate treaties and alliances, but public opinion shapes the political environment in which those decisions are possible. Citizens, therefore, require reasonably accurate perceptions of the international system. Historically, those perceptions have emerged from multiple sources: education, journalism, diplomacy and direct human experience.
Today, another actor has quietly entered that process. Algorithms.
Recommendation systems increasingly determine which countries appear in our news feeds, which conflicts attract our attention, which voices become visible, and which remain unheard. Their objective is not deception. Nor is it education. It is engagement. The distinction is critical.
Algorithms rarely invent reality. They organise it, prioritising some experiences while rendering others nearly invisible.
As a result, two individuals travelling through the same country may return home with markedly different understandings—not because they observed different realities, but because they inhabited different digital environments throughout their journey.
Geography, in other words, is no longer determined solely by physical distance. It is increasingly shaped by digital mediation.
Why this matters for geopolitics
The implications extend far beyond communication technologies. International relations ultimately depend on perception.
Public support for alliances, sanctions, humanitarian assistance, military commitments, immigration policies and international cooperation all presupposes some understanding of foreign societies.
When that understanding increasingly stems from algorithmically curated information rather than lived experience, democratic debate changes. This is not an argument against digital technology. Nor is it a nostalgic call to return to a pre-digital world. Rather, it is an invitation to recognise a strategic transformation that has received relatively little attention.
Throughout modern history, millions of ordinary citizens unknowingly engaged in informal diplomacy. Every journey abroad, every exchange semester, every scientific collaboration and every unexpected conversation offered opportunities to test assumptions against reality. The cumulative effect of those encounters is difficult to measure. Yet it may have been one of democracy’s most underestimated sources of resilience. Direct experience does not eliminate prejudice or misinformation, but it introduces something that algorithms often struggle to provide.
Context.
Complexity.
Human contradiction.
Reality.
The geography of perception
Perhaps the defining geopolitical challenge of the twenty-first century is not simply the protection of critical infrastructure, cybersecurity or information integrity. It may also involve safeguarding the conditions under which democratic societies acquire first-hand knowledge of the world.
Globalisation promised to reduce the distance between people.
In many respects, it has.
Yet another form of distance has quietly emerged—not measured in kilometres, but in algorithms. The challenge before us is therefore no longer whether citizens can travel farther than previous generations. It is whether they continue to encounter reality before it is interpreted for them.
That question deserves far more attention than it has received so far, because the resilience of democratic societies ultimately depends not only on access to information but also on access to experience.
And in an age increasingly shaped by algorithmic mediation, preserving opportunities for genuine human encounter may prove to be one of the least recognised—but most important—strategic investments of all.
