"Assumptions are dangerous illusions that bind us to an unsuccessful future." - Futurist Jim Carroll

In a world of exponential change, what you *think* you know is often your greatest liability.

That's because your ability to rely on assumptions offers a false promise of progress.

Why? Because if you are still operating on last year’s logic, you aren't just behind - you are watching a different movie entirely. You must dismantle your assumptions before they become organizational vulnerabilities.

I took a look at what I've written about the danger of assumptions, and came up with this list of 10 reasons why assumptions are dangerous to your success. Each reason contains one of my Jim-isms - a unique word or phrase I've coined in previous posts. I've underlined them for emphasis.

  1. They Create Scale-Blindness: We are wired for linear addition, but the future is built on multiplication. Read my series for 2026 about exponential change. Assumptions leave you blind to the exponential tsunamis heading for your industry.
  2. They Fuel Aggressive Indecision: The assumption that waiting for "perfect clarity" is safe leads to organizational sclerosis. In a volatile world, clarity is a myth.
  3. They Anchor You to "The Olden Days": The hubris of experience suggests that because a strategy worked for 30 years, it will work tomorrow. Today, that experience is often just a heavy anchor.
  4. They Blind You to "The Blur": We assume industry boundaries are fixed. The future happens in the blur between lines, where new competitors reinvent your model while you stay in your lane.
  5. They Lead to Innovation Sclerosis: "We’ve always done it this way" is a red flag for an abandoned future. It prioritizes process over the imagination required to survive.
  6. They Result in Strategic Hubris: Success leads to the illusion of invincibility. The moment you assume you have a "magic touch," you stop listening to the market signals that matter.
  7. They Ignore the Wisdom Inversion: Hierarchy assumes seniority equals foresight. In reality, your youngest employees often have a clearer intuitive grasp of what’s next than the C-suite.
  8. They Trap You in Pilot Purgatory: The assumption that you have years to roll out a "safe test" is a trap. You must move from experiment to massive deployment instantaneously.
  9. They Create a Bunker Mentality: Many assume they can hunker down and wait for "normal" to return. It isn't coming back. Waiting is a suicide pact built on a fundamental misunderstanding of change.
  10. They Rely on the Informed Delusion: We assume more data equals better decisions. Often, more data simply increases your *belief* in your existing assumptions while the world shifts beneath you.

The bottom line?

The moment you think your future is guaranteed is the moment it becomes certain that it isn’t!

Stop planning for the probable and start preparing for the unimaginable.

Futurist Jim Carroll believes that assumptions are the root cause of many innovation failures.
