Ideological Priors Inventory

“As I step into the state space in my mind’s eye, I imagine that the fifteen-dimensional landscape of pixel dots has somehow been converted into our three-dimensional world and now resembles a terrain we might find on Earth, with a pixelated topography of mountains, valleys, plains, and cliffs. I call this place the ‘mindscape’: it’s the geography of all possible human worldviews.” —Thomas Homer-Dixon, Commanding Hope (309-10)

A multidimensional tool for understanding worldviews 

The Ideological Priors Inventory is an innovative survey instrument that maps the deep beliefs and values shaping how people navigate the world. Originally introduced by Thomas Homer-Dixon in his 2020 book Commanding Hope, the Ideological Priors Inventory is a practical 16-item survey tool developed in collaboration with the Canadian polling firm Environics and tested across Canada and the United States. 

Unlike traditional ideology measures that reduce complex beliefs to simple Left-Right categories, the Ideological Priors Inventory reveals worldviews across multiple dimensions—including Order-Chaos, Hierarchy-Equality, Tradition-Innovation, and Individualism-Collectivism.

By placing individuals and groups in this multidimensional "ideological state space," the Ideological Priors Inventory makes it possible to visualize how worldviews differ across communities.

We believe that such analysis could expose unexpected areas of similarity or conflict, and identify entirely new worldviews that are better aligned with a more resilient and hopeful world. 

This instrument has broad potential applications: helping organizations engage constructively across ideological divides, enabling conflict-sensitive communication, supporting democratic dialogue, and providing researchers with a more nuanced understanding of how core beliefs connect to attitudes and behaviours on complex policy issues. 

Ideological Priors and the Energy Transition 

The Cascade Institute is currently applying the Ideological Priors Inventory to understand how worldviews shape public responses to the shift to clean energy amid escalating climate risks. By examining how the Ideological Priors Inventory's core belief dimensions relate to real-world energy decisions—from the permitting of geothermal and wind projects to the upgrading of grid infrastructure—this project provides practical guidance for communities, energy planners, and policymakers seeking to accelerate the transition while reducing polarization. 

The project is producing peer-reviewed research, an interactive web demonstration tool, and practical briefings that show how to align energy initiatives with community values, identify potential flashpoints before they escalate, and engage more effectively across ideological differences.  

By understanding not just what people believe but how their worldviews are structured, the Ideological Priors Inventory helps navigate the ideological dimensions of energy transition with greater insight and less conflict.
