For decisions where being wrong is expensive. Free tools give you fast clarity. Advanced assessments and tools are built for moments where the downside is real.

When stakes are low, speed matters. When stakes rise, rigor matters more.

Advanced assessments and tools are:

  • Deeper and more comprehensive

  • Designed to expose hidden risk and second-order effects

  • Built for decisions you don’t get to redo

This is not daily hygiene.

This is decision insurance.

What you unlock.

  • Built to pressure-test judgment when the margin for error is thin.

    • Risk Asymmetry Test

      Reveal where upside is capped and downside is quietly lethal.

    • Decision Integrity Assessment

      Expose bias, misalignment, sunk costs, and ego interference.

    • Irreversibility Assessment

      Identify one-way doors before you treat them like two-way doors.

  • Designed to force resolution, not reflection.

    • Tradeoff Clarifier

      Name the real cost you’re avoiding admitting.

    • Commit or Kill Gate

      Decide, delay with rules, or exit cleanly.

    • Second-Order Impact Mapper

      See downstream consequences before they compound.

  • Advanced Access includes unlimited use of all advanced assessments and tools.

“The illusion that we understand the past fosters overconfidence in our ability to predict the future.”
