The Hidden Psychology Behind Phishing Simulations: Why Employees Still Click

Phishing simulations are a core component of cybersecurity training programs, yet many employees continue to fall for them. This isn’t simply a failure of awareness or policy—it’s a reflection of how human psychology works.

Clicking on a phishing email often happens in a split second, driven by emotions like urgency, fear, curiosity, or trust. These are natural human responses that cybercriminals exploit through carefully crafted messages. If simulations don't mirror these emotional triggers, they lose their effectiveness.

According to the 2025 Data Breach Investigations Report by Ventures, human error was behind nearly 60% of breaches—proving that people, not systems, remain the weakest link. This reinforces the need to understand not just what phishing looks like, but why people fall for it.

In this blog, we’ll explore the psychological reasons why employees still click, examine the cognitive traps embedded in phishing emails, and share how organizations can create simulations that truly reshape behavior.

Why Employees Still Click – A Psychological Breakdown

Understanding why employees continue to click on phishing emails—even after repeated training—starts with understanding how the human brain processes information. Attackers don’t just target systems; they exploit how we think, react, and decide in the moment.

The Role of Cognitive Biases in Clicking Behavior

Psychologist Daniel Kahneman, in his book Thinking, Fast and Slow, explains that we use two types of thinking:

System 1, which is fast, automatic, and emotional, and System 2, which is slow, deliberate, and logical.

Phishing emails are designed to trigger System 1, making people click instinctively—often before they’ve had a chance to think things through.

Attackers commonly exploit the following cognitive biases:

• Authority bias: Impersonating executives or IT staff to prompt immediate compliance.
• Curiosity: Using vague subject lines like “Important update” or “Confidential report.”
• Urgency: Creating time pressure with phrases like “Your account will be locked in 24 hours.”
• Loss aversion: Threatening data loss or missed opportunities to provoke action.
• Trust triggers: Mimicking well-known brands or internal systems to lower suspicion.

A phishing scenario from the Keepnet Phishing Simulator puts this into action. One simulation sends a message titled “Important: Cyber Security Policy Violation,” warning the user of non-compliance and featuring a red “Review Cybersecurity Policy” button. The message threatens suspended access if no action is taken. This single email activates several psychological triggers at once—authority (from IT or compliance), urgency (with a deadline), loss aversion (risk of losing access), and trust (due to its formal tone and internal branding)—making it highly effective at provoking a quick, unthinking response.

When Trust Becomes a Weapon

Phishing attackers often exploit the halo effect—a cognitive bias where people trust messages that appear to come from familiar or authoritative sources. By mimicking trusted brands, internal departments, or known colleagues, attackers create emails that feel legitimate at first glance.

These emails often include company logos, formal language, or internal references to make them look authentic. In a busy workday, even small cues—like a familiar sender name or a standard email signature—can lower an employee’s guard.

This misplaced trust is exactly what phishing simulations aim to expose. When employees rely on how an email “feels” instead of verifying its source, attackers gain the upper hand.

Curiosity and Overload: The Daily Email Trap

Employees receive dozens, sometimes hundreds, of emails each day. In this constant flow of communication, they rely on quick decisions to stay productive—often clicking without fully analyzing the content.

Phishing attackers take advantage of this cognitive overload by crafting emails that resemble everyday work messages. Subject lines like “Updated invoice” or “Shared document” spark curiosity and blend into the normal email routine, making them easy to overlook as threats.

When employees are busy or distracted, their instinct to click takes over. That’s when even trained users can fall for convincing phishing attempts.

The Limits of Traditional Training and Simulations

Traditional phishing training often falls short because it doesn’t reflect how people behave under pressure. When simulations rely on predictable formats or once-a-year modules, employees quickly tune out—and the lessons don’t stick. To truly reduce human risk, organizations need smarter, more dynamic training that adapts to user behavior and evolving attack techniques.

Why Annual Training Isn’t Enough

Annual cybersecurity training may meet compliance standards, but it doesn’t meaningfully reduce human risk. A study by UC San Diego and the University of Chicago, involving over 19,500 employees, found no significant difference in phishing click rates between those who had recently completed training and those who hadn’t. This highlights a critical flaw in traditional training: once-a-year sessions simply don’t change behavior.

The problem gets worse when simulations rely on generic, recycled content. Employees start recognizing the format instead of learning how to detect actual phishing threats. This leads to overconfidence—they pass the test, but they’re not prepared for real attacks.

To truly reduce risk, security awareness training must be continuous, context-specific, and adaptive—encouraging users to engage critically, not just recognize familiar patterns.

Phishing Simulation Fatigue and Overconfidence

Repetitive phishing simulations can backfire. When employees are exposed to the same formats over and over, they stop paying attention. This leads to simulation fatigue—where users no longer take the training seriously because it feels predictable or irrelevant.

At the same time, a zero-click rate in simulations may seem like success, but it can be misleading. If simulations are too easy or obvious, employees might not be learning anything new. Worse, it can create false confidence, making users think they’re prepared when they’re not.

Effective training shouldn’t aim for perfect scores. It should challenge users, simulate real decision-making under pressure, and uncover hidden gaps in awareness.

Making Phishing Simulations More Effective Through Psychology

To build real cyber resilience, phishing simulations need to go beyond templates and test scores. They should be rooted in how people think and behave under pressure. By applying psychological principles, organizations can design smarter simulations that truly change behavior—not just measure it.

Behavioral Design for Security

Phishing simulations are most effective when they feel relevant. That starts with personalized, adaptive content tailored to each employee’s role in the company. A financial analyst may receive fake wire transfer requests or invoice fraud emails, while a help desk agent might be targeted with fake password reset tickets or internal IT spoofing. Likewise, executives could face spear-phishing attempts disguised as board communications. Effective training reflects these unique risks by adjusting simulations not only by department, but also by access level and responsibility.

Emotional triggers like curiosity, fear, urgency, and trust should be intentionally woven into each simulation. These are the same psychological levers real attackers use. Training that mirrors these cues helps employees build instinctive, in-the-moment decision-making skills—not just pattern recognition.

Build a Culture of Safe Reporting

Training shouldn’t punish mistakes—it should turn them into learning moments. If employees fear blame for clicking, they’re less likely to report real threats.

Instead, foster a culture where reporting is rewarded and seen as part of everyday responsibility. Use positive reinforcement and gamified elements to keep engagement high and reduce the stigma around making errors during simulations.

Measure More Than Click Rates

Click rates are just the starting point. The real value lies in what employees do next. Do they report the suspicious email? Enter credentials? Close the browser? These actions reveal whether someone understands the risk—or just avoided it by chance.

To improve behavior, simulations should not only track these responses but also guide users in the moment. This is where behavioral nudges play a critical role. A well-timed message after a click can prompt reflection, encourage reporting, or correct risky behavior—without shaming the user. Over time, these subtle interventions help reinforce better habits.

By combining behavioral insights with smart nudges, organizations can build stronger awareness, tailor support to specific needs, and drive real cultural change—far beyond basic click-through metrics.

Turning Clicks Into Learning Opportunities

Clicking a phishing email isn’t necessarily a failure—it’s a valuable learning opportunity. When simulations are informed by behavioral psychology and followed by timely feedback, they help employees develop stronger awareness and better decision-making skills.

Building cyber resilience requires more than one-time training or penalties. It depends on consistent, adaptive education that reflects how people naturally think and react under pressure.

Leaders should shift their focus from achieving perfect scores to driving measurable behavior change. The goal isn’t zero clicks—it’s helping employees recognize risks earlier, respond correctly, and grow more confident with every simulation.
