Contrail Tiebreaker

It’s a high-flying race between the fossil-fuel champions being challenged by the champions of hydrogen fuel. Who will soar to victory? Welcome to Tiebreaker Tuesday, where we show how the editors and POLI THE AI worked out their differences. (5 min)

The Problem

Countries bordering mountains that depend on the runoff to feed their streams will become desperate for water when the ice caps melt.

A solution is to convert all long-haul flights to hydrogen fuel, which would water the planet with the equivalent of one or two Lake Tahoes a year. The extra humidity will help refreeze the poles and re-snow mountain caps. You can read more about it in our intro article.

One-Page Narrative Tool

We utilize a standardized method to vet public policy solutions and give them a nonpartisan score.

AI and humans forecast the level of support or opposition from 128 societal roles and explain why in the simplest terms possible.

The Tiebreaker article shows where the humans broke an AI tie or disagreed with the AI. There’s a link to our methodology at the bottom of this article.

POLI THE AI had these roles without a general bias for the status quo or change when it comes to our hydrogen airplanes solution. The editors use specific reasons to break the tie.

We’re predicting that most people in these roles would either say YES or NO, but not all.

Nonpartisan Score for Hydrogen Planes has

POLI found STRONG SUPERMAJORITY support. Our editors agreed but were slightly less optimistic.

We predict a 71% ±4 (11 roles) 
STRONG SUPERMAJORITY of roles in this country to support HYDROGEN PLANES TO PREVENT WATER WARS, including a majority of each of the four sides of the political tablemaking this a US Public Policy Leaderboard (US-PPL) worthy idea. 

90% and up Near Unanimous
80% – 89% Near Consensus
75% -79% Vast Supermajority
60% – 66% Supermajority
50% – 59% Majority


SCOTUS’s approval rating is 41%,
the media is 32%, and
Congress is 15%.

Do we expect you to agree with the supermajority on all the rankings? Of course not; you’re human, not a hyper-partisan parrot.

We think you’ll agree with the leaderboard about 3 out of 4 items on average. Why?

The average score of the policies on the PolicyKeys™ US Public Policy Leaderboard (US-PPL) Sweet Sixteen is 76%, with many above 80%Politics 4.0 is already a 2x to 5x better model of US political sentiment and direction than politics as usual.
