The Cassandra Effect - When Being Right Isn’t Enough

The Cassandra Effect - When Being Right Isn’t Enough

In Greek mythology, Cassandra was cursed to see the future clearly, but never be believed.

She spoke the truth, warned others, and she was ignored.

I first heard this idea discussed on the Modern Wisdom podcast, in conversation with Chris Williamson and Andrew Huberman, and it stopped me in my tracks.

The pattern still shows up everywhere today.

In coaching, the Cassandra Effect appears when someone can clearly see what’s coming (a failing strategy, a misaligned role, a cultural issue) but feels unheard, dismissed, or quietly sidelined.

The cost isn’t just frustration.

It’s erosion of self-trust.

People start asking:

  • “Am I overreacting?”

  • “Maybe I’m the problem.”

  • “What’s the point of speaking up?”

This is where coaching matters.

Rather than focusing on whether others believe them (or not), the work shifts to:

  • Reconnecting with their own clarity

  • Separating truth from needing validation

  • Exploring how insight is shared,and when it’s wise to stop pushing

Powerful coaching questions here include:

  • “What do you know to be true, even if others can’t see it yet?”

  • “What’s in your control, and what isn’t?”

  • “How do you stay grounded without needing agreement?”

Not every truth is immediately welcomed. If this were a longer piece I would give several examples such as the ‘O’ rings that led to the Space Shuttle disaster.

However for now, just know that clarity, held calmly and without resentment, has its own authority.

Your aim isn’t to convince everyone.

It’s to stay aligned with what you see, without losing yourself in the process.

Sometimes the most courageous leadership move is this:

Speak the truth … and remain steady when it isn’t received.

Remember, the path to extraordinary is walked with a thousand small steps, you’re doing great!
