Key idea 1 of 7

What’s in it for me? Learn how harmful ideologies threaten reason and intellectual freedom.

Modern society faces a new kind of pandemic – one not caused by biological pathogens, but by a collection of dangerous ideas. These “idea pathogens” threaten to erode reason, freedom, and intellectual diversity. Spawned on university campuses, they spread into politics, business, and culture, challenging the foundations of rational thought and discourse.

Author Gad Saad contends that this pandemic of disordered thinking stems from a tendency to let emotions override reason. Institutions that should be committed to truth-seeking, such as universities, are increasingly fostering ideologies that reject science and intellectual freedom in favor of conformist thinking. The consequences are profound, impacting every facet of society.

In this Blink, you’ll explore how these destructive ideas take root, why they pose a grave danger to free inquiry, and the steps necessary to reclaim reason and critical thinking in an era dominated by intellectual conformity. Let’s begin.

Defending truth and freedom

What drives a person to stand against the tides of societal conformity? For Gad Saad, it’s a deep commitment to freedom and truth. His early life in war-torn Lebanon exposed him to the dangers of tribalism and identity politics, teaching him how these forces can curb reason and dehumanize individuals.

This experience laid the groundwork for his lifelong resistance to ideological conformity – and defined his academic career. Unlike many who confine themselves to a single niche, Saad embraces intellectual curiosity, exploring varied fields and challenging norms. His belief in the pursuit of truth compels him to engage openly with the public, despite the risks of defying academic expectations.

Saad posits that universities, which should foster such intellectual exploration, have instead become breeding grounds for ideologies that resist reason. He identifies these institutions as epicenters for movements like postmodernism and radical feminism, which stray from scientific rigor and objective thinking. He describes these ideologies as “mind viruses” that create environments where free inquiry is stifled, and conformity is rewarded.

Saad sees this issue as part of a broader cultural struggle in the West: the battle between reason, freedom, and open discourse versus the rise of political correctness, identity politics, and thought policing. He calls this conflict the “death of the West by a thousand cuts,” as various forces slowly erode the principles of intellectual freedom and truth.

To counter this decline, Saad argues for a return to critical thinking rooted in science and logic. If we renew our focus, he believes, there is still hope for reclaiming intellectual freedom and resisting the spread of the so-called ideological parasites.

How emotions undermine rational decision-making in society

Have you ever wondered why people struggle to balance reason and emotion in their decisions? It’s tempting to view things in binary terms, such as thinking versus feeling, but this oversimplification can lead to flawed decisions.

In reality, humans are both thinkers and feelers, and the key is knowing when to engage either the cognitive or emotional part of the brain. Some choices, like investing in a mutual fund, call for careful thought, while impulse buys rely more on feelings. The real issue arises when we apply the wrong type of processing – using emotions for decisions that demand logic.

Free speech as the foundation of a free society

What does it mean to live in a truly free society? At its core, it’s the ability to express any idea, no matter how contentious, without fear of suppression. The foundation of a liberal and modern society rests on freedom of speech and thought. This open exchange of ideas, tested by reason and science, has driven the progress of Western civilization. Without the liberty to challenge prevailing notions, society risks losing its grasp on truth.

Today, social media companies wield enormous power over public discourse. They act as gatekeepers, deciding which voices can be heard and which are silenced. Right-leaning perspectives are often suppressed through demonetization, bans, and algorithmic biases. The influence of these companies extends far beyond traditional media, prompting calls for regulation to prevent them from becoming unchecked arbiters of free expression.

When ideology replaces reality and rejects scientific truths

What happens when ideology overrides reality? Many modern movements, especially those prominent in academic circles, have adopted views that reject established scientific truths in favor of personal or political beliefs. These include postmodernism, social constructivism, radical feminism, and certain facets of transgender activism.

The result, Gaad argues, is an erosion of reason as objective facts give way to subjective narratives. For instance, transgender activism sometimes denies the biological reality of sex – it says that gender identity can fluctuate daily, leading to legal changes where misgendering is treated as a hate crime.

How victimhood culture stifles free speech on campuses

What happens when a culture prioritizes feelings over facts, and victimhood becomes a badge of honor? On many college campuses, a small but vocal group of activists – often referred to as social justice warriors, or SJWs – dominate the narrative. These individuals, supported by some faculty and administrators, push a climate of extreme political correctness. Here, being part of an oppressed group grants social standing, resulting in a hierarchy of victimhood. As a result, the pursuit of knowledge takes a backseat to managing grievances and perceived slights.

This atmosphere has led to the establishment of “safe spaces,” where opposing views are silenced. Universities, traditionally places for robust debate, have turned into echo chambers. The combination of students claiming that differing opinions are a form of violence and professors leaning toward one ideology has created an environment where intellectual growth is stifled. Without exposure to diverse perspectives, students are ill-equipped to think critically and handle disagreement.

The dangers of denying scientific facts for comfort

In 1998, a study falsely claimed a link between the MMR vaccine and autism. Though later retracted, it ignited an anti-vaccine movement led by celebrities who found it easier to blame vaccines for autism than accept that their children might have a genetic predisposition.

This refusal to accept established science shows a broader human tendency: the denial of uncomfortable truths. People often create alternate realities, dismissing scientific consensus for the comfort of personal beliefs. This is described as ostrich parasitic syndrome, where facts as obvious as gravity are rejected in favor of comforting illusions.

How to seek truth through diverse evidence and reasoning

What does it take, then, to seek the truth in today’s complex world? Many people find this task challenging due to their tendency to cling to familiar beliefs and avoid information that contradicts their views. Often, once a person has formed an opinion, they resist considering alternative perspectives – even in the face of compelling evidence. This resistance is driven by cognitive biases and emotional investment, making the quest for objective understanding difficult.

To break through this stubbornness, you need to employ a rigorous method for gathering and synthesizing knowledge from various fields. A powerful way to achieve this is by building networks of cumulative evidence. This approach mirrors the way scientists conduct research, drawing from diverse sources and different types of evidence. By piecing together information from many angles, an argument becomes more robust and harder to dismiss. Darwin’s work on evolution is a prime example – he gathered evidence from biology, geology, and anatomy to build an irrefutable case.
