The Psychology of Security Failures: Why Smart People Keep Making the Same Stupid Mistakes
Noel spent Monday and Tuesday explaining what reverse benchmarking is and how to implement it technically. Both excellent. Both necessary. Both completely inadequate if you don't understand why organizations systematically fail to learn from disasters.
Because here's the uncomfortable truth: most breaches happen not because organizations don't know what to do, but because human psychology actively prevents them from doing it.
Let me explain why, and more importantly, what you can do about it.
The Normalcy Bias: Why "It Won't Happen to Us" Persists Despite Evidence
The National Cyber Security Centre says half of UK SMBs will experience a breach this year. Coin flip odds.
Yet when I talk to business owners, 90% believe they're in the safe half. This isn't stupidity. It's normalcy bias: the cognitive tendency to believe that things will function normally, and that disasters are unlikely to occur.
The Psychological Mechanism
Your brain evolved to ignore constant low-probability threats because otherwise you'd be paralyzed with anxiety. This worked brilliantly for avoiding predators in the savanna. It fails catastrophically for cybersecurity, where:
Threats are invisible until they materialize
The probability is actually quite high (50% annually)
The impact is severe (60% of breached SMBs close within six months)
Your risk assessment instincts are calibrated for a world that no longer exists.
Why This Matters for Reverse Benchmarking
When Noel says "study these breaches and learn from them," your brain hears "study these rare anomalies that happened to other people." The psychological distance prevents genuine learning.
The Target breach happened to a massive retailer. You run a 20-person consultancy. Your brain files it under "not relevant to me" and moves on.
This is exactly backwards. The lessons are more relevant precisely because you're smaller. Target survived. You won't.
The Fix: Personalization
Don't study breaches as abstract case studies. Run tabletop exercises where YOUR company experiences the breach.
Not "what happened to Target?" Ask "what happens when OUR HVAC contractor's credentials get stolen?"
Walk through it step by step:
Do they have network access? (Check right now. I'll wait.)
What systems can they reach?
Is their access monitored?
Do they have MFA?
When it's YOUR data, YOUR customers, YOUR business closure, the normalcy bias breaks. The threat becomes real.
Optimism Bias: The Dangerous Delusion of Control
60% of UK businesses lack formal cybersecurity incident management plans. These same businesses have fire evacuation plans, electrical safety certifications, and health and safety policies.
Why the discrepancy?
Optimism bias: the belief that we're less likely to experience negative events than others, particularly for events we feel we can control.
The Psychology
You can see the fire exit. You can watch employees evacuate during a drill. You can touch the fire extinguisher.
Cybersecurity is invisible. You can't see the firewall working. You can't watch MFA preventing an intrusion. The lack of visible feedback creates the illusion that nothing needs to be done, because nothing appears to be happening.
Absence of evidence becomes evidence of absence.
Why This Kills Organizations
Colonial Pipeline had cybersecurity people. They had budgets. They had policies. They still got ransomed because someone decided VPN MFA wasn't urgent.
That decision wasn't stupidity. It was optimism bias. "We haven't been breached yet, so our current measures must be adequate."
The absence of a breach was interpreted as evidence of security, rather than evidence of luck.
The Fix: Negative Visualization
Stoic philosophers practiced negative visualization: regularly imagining worst-case scenarios to reduce their psychological impact and prepare for them.
Apply this to cybersecurity:
Monthly Exercise (15 minutes):
Imagine your business experiencing a specific breach type:
Week 1: Ransomware encrypts all your systems
Week 2: Customer database stolen and published
Week 3: CEO's email compromised and used for fraud
Week 4: Vendor breach exposes your data
For each scenario, write down:
How you'd discover it
What immediate actions you'd take
Who you'd need to contact
What systems you'd need to isolate
How you'd communicate with customers
This isn't pessimism. It's preparation. And it breaks optimism bias by forcing you to concretely visualize the scenarios your brain wants to dismiss.
The Fundamental Attribution Error: Why Blame Prevents Learning
When Equifax got breached because they didn't patch for two months, the industry reaction was predictable: "Those idiots! How could they be so incompetent?"
When your organization has unpatched systems (which it probably does), the explanation is different: "We're understaffed. The patch might break things. We need to test it first. We'll get to it next quarter."
This is the fundamental attribution error: we attribute others' failures to incompetence or character flaws, while attributing our own failures to situational factors.
Why This Destroys Security Culture
If breaches happen because other people are incompetent, then studying breaches becomes an exercise in feeling superior. "We'd never be that stupid."
But you would. You will. You probably already have been.
The Equifax security team wasn't dumber than you. They were dealing with the same organizational dysfunction, competing priorities, and resource constraints you face every day.
The Psychology of Blame Cultures
Organizations with blame cultures have:
Lower reporting of security incidents
Higher employee turnover in security roles
Slower response times when incidents occur
More repeat incidents of the same type
Why? Because when failure = punishment, people hide failures.
Janet in accounting falls for a phishing email. In a blame culture, she deletes it and hopes nothing happens. The IT team never knows. Six months later, the ransomware activates.
In a no-blame culture, Janet reports it immediately. IT isolates her machine, checks for malware, blocks the sender, and sends a company-wide warning with specific details about what the phishing attempt looked like.
One person's mistake becomes everyone's education.
The Fix: Blameless Post-Mortems
Aviation has the right model. When there's a near-miss or incident:
Fact-gathering without blame: What happened? What was the sequence of events?
System analysis: What systemic factors contributed? Not "who screwed up" but "what conditions allowed this to happen"?
Process improvement: What changes prevent recurrence?
Knowledge sharing: How do we ensure everyone learns from this?
Notice what's missing: punishment.
The goal isn't to make people feel bad. The goal is to prevent the next incident.
Implement this for ANY security incident or near-miss:
Phishing test failure → Blameless debrief with specific education
Unpatched system discovered → Systemic review of patch management process
Weak password found → Review of password policy enforcement mechanisms
Vendor with excessive access → Audit of ALL vendor access
Every failure is a learning opportunity. But only if blame doesn't prevent the learning.
The Availability Heuristic: Why Recent Breaches Get Attention While Systemic Risks Don't
The availability heuristic is the cognitive bias where people overestimate the probability of events that are easily recalled, usually because they're recent, dramatic, or emotionally charged.
How This Manifests in Cybersecurity
When a major breach hits the news, suddenly everyone wants to address that specific attack vector. SolarWinds supply chain compromise happens, and everyone's talking about vendor risk.
Three months later, the news cycle moves on. The vendor risk assessments sit half-finished in a SharePoint folder nobody visits.
Meanwhile, the boring systemic issues (unpatched systems, lack of MFA, poor access controls) that cause most breaches get ignored because they're not exciting.
The dramatic gets attention. The foundational gets ignored. Organizations get breached.
Why Reverse Benchmarking Fights This
By systematically reviewing breaches rather than reacting to headlines, you override the availability heuristic.
The Target breach is from 2013. Still relevant. Still teaching vital lessons about vendor access. Not trending on Twitter. Still matters.
The Fix: Structured Review Process
Don't let your security priorities be determined by what's trending. Create a structured process:
Monthly breach review: Pick one significant breach from the past five years. Doesn't matter if it's "old news." What matters is whether you've learned the lessons.
Quarterly priority review: Are we addressing systemic risks or just reacting to headlines?
Annual threat assessment: What are the actual attack vectors affecting our industry, based on data rather than news coverage?
This isn't glamorous. It's boring. That's why it works.
The Planning Fallacy: Why "We'll Get to It Next Quarter" Means Never
The planning fallacy is the tendency to underestimate how long tasks will take, despite knowing that past predictions were too optimistic.
How This Destroys Cybersecurity
"We'll implement MFA next quarter" becomes "We'll do it after the busy season" becomes "We'll do it in the new year" becomes "We got ransomware."
Colonial Pipeline probably had VPN MFA on the roadmap. Roadmaps don't stop ransomware.
The Psychology
Your brain is optimistic about future capabilities ("we'll have more time next quarter") while being realistic about current constraints ("we're too busy now").
Spoiler: You won't have more time next quarter. You never do.
The Fix: Minimum Viable Security
Stop waiting for perfect conditions to implement comprehensive security programs. Start implementing minimum viable controls today.
MFA on your VPN doesn't require budget approval, vendor assessments, or comprehensive testing. It requires 2 hours of admin time and £0-10 per user per month.
Do it today. Not next quarter. Today.
The perfect comprehensive security program you'll implement next quarter is worth exactly zero compared to the basic control you implement this afternoon.
The Sunk Cost Fallacy: Why Bad Decisions Persist
Your organization has been using the same VPN solution for eight years. It doesn't support MFA. Replacing it would cost money and cause disruption.
So you keep using it, despite knowing it's inadequate.
This is the sunk cost fallacy: continuing a behavior because of previously invested resources, even when continuing is irrational.
Why This Kills Security Efforts
"We've already invested in this security tool" becomes the reason to keep using an inadequate security tool, rather than the reason to replace it.
The money is spent. It's gone. The only relevant question is: does this tool meet our current security needs?
If the answer is no, replacing it isn't "wasting" the previous investment. It's preventing the future investment in incident response after you get breached.
The Fix: Regular Zero-Based Review
Once per year, review every security tool and control as if you were choosing it for the first time today.
Question: If we didn't already have this, would we buy it now?
If the answer is no, start planning the replacement. Don't let sunk costs determine your security posture.
The Illusion of Understanding: Why Compliance Feels Like Security
You've implemented Cyber Essentials. You feel more secure. Your actual security posture hasn't changed materially.
This is the illusion of understanding: the belief that we comprehend complex situations better than we actually do.
How Compliance Creates This Illusion
Compliance frameworks provide a checklist. Checkboxes get ticked. Progress is visible. Accomplishment feels real.
But compliance ≠ security.
Compliance is passing the driving test. Security is not crashing your car. They're related but not equivalent.
The Psychology
Your brain craves certainty and completion. Compliance frameworks provide both: clear requirements, objective measures of completion.
Real security provides neither: uncertain threats, evolving attack methods, no clear endpoint where you're "done."
The false certainty of compliance is psychologically more satisfying than the honest uncertainty of actual security.
The Fix: Threat-Based Rather Than Compliance-Based Thinking
Instead of "Have we met Cyber Essentials requirements?", ask "What threats are we actually facing, and what controls actually prevent them?"
The first question has a comforting yes/no answer. The second question is uncomfortable and never fully resolved.
Embrace the discomfort. It's where actual security lives.
Bringing It All Together: The Psychology-Aware Approach to Reverse Benchmarking
Noel's reverse benchmarking framework is technically sound. But it fails without understanding the psychology that prevents organizations from implementing it.
Here's the psychology-aware version:
1. Personalize Every Breach
Don't study "the Target breach." Study "what happens when OUR vendor gets compromised."
Use YOUR company name, YOUR systems, YOUR data in the analysis. Break normalcy bias by making it concrete and personal.
2. Practice Negative Visualization
Monthly 15-minute exercise: vividly imagine specific breach scenarios affecting your business. Write down your response plan.
This breaks optimism bias and creates psychological preparedness.
3. Implement Blameless Post-Mortems
Any security incident or near-miss gets analyzed for systemic factors, not individual blame.
Create a culture where reporting security issues is praised, not punished.
4. Structured Review Over Headlines
Don't let news cycles determine your priorities. Systematic monthly review of historical breaches provides better learning than reactive responses to current events.
5. Minimum Viable Security Today
Stop planning comprehensive programs for next quarter. Implement basic controls this week.
The planning fallacy guarantees next quarter never comes. Act now.
6. Annual Zero-Based Review
Ignore sunk costs. Evaluate every security tool and control as if you were choosing it fresh today.
7. Threat-Based Thinking
Compliance is useful but insufficient. Focus on actual threats and effective controls, even when that's psychologically uncomfortable.
The Hard Truth
The reason organizations fail at cybersecurity isn't lack of knowledge. The Target breach lessons have been public for over a decade. Organizations still repeat the same mistakes.
The reason is psychology. Our brains evolved for different threats in different environments. The cognitive biases that kept us alive on the savanna now get us breached in the digital world.
You can't eliminate these biases. They're hardwired. But you can design processes that account for them, work around them, and prevent them from destroying your security posture.
That's the real value of reverse benchmarking: not just learning what went wrong, but understanding why smart people keep making the same stupid mistakes, and creating systems that prevent you from joining them.
Tomorrow, Noel will cover practical implementation tools for SMBs. But tools without psychology awareness are just expensive ways to feel secure while remaining vulnerable.
Fix the psychology first. The tools will be more effective.
