I think the easiest way to recount the ideas we worked on is to place them in the context of the company timeline. I’ll outline the key company milestones here and for each, I’ll link to an article that dives deeper into the key ideas we were pursuing or how our technology worked.

March 2014: Initial Ideation

Considdr was born in a strange moment of existential anxiety. I had just started spring break of my sophomore year in college after finishing a particularly grueling set of midterm exams. I collapsed in the reclining chair in my living room and reflected on the sheer volume…


Today’s search engines are very good at surfacing relevant information, but finding that information is really just step one: distilling it, synthesizing it, and applying it to build more informed beliefs make up a large part of the knowledge acquisition journey.

Logical Aggregation and Belief Trees are Considdr’s attempt at the synthesizing and belief-building stages. This article covers the distilling step.

How do we best distill the world’s knowledge?

This monumental question really sits at the foundation of Considdr’s mission. It’s about figuring out what’s most important from any source of information and expressing it in a concise format. Here are a few other ways to frame this…


If you’re coming to this post without first reading the overview post: “Considdr Milestones”, I’d highly recommend starting there to gain appropriate context for what follows.

Intro to Logical Aggregation

Logical Aggregation is a new approach to organizing information by expressing that information in terms of the questions it may address, the arguments it puts forth, and the evidence it uses to back up those arguments. It figures out which arguments and evidence are most relevant to any given question based on the meta-data produced by the Belief Tree building process.

Expressing all information this way — in terms of questions, arguments, and evidence…

A theoretical introduction to Belief Trees and a walkthrough of Belief Tree building in the first MVP of Considdr in 2016 (first called “The Market of Ideas”).

Belief Trees

Belief Trees were envisioned as a way to build, store, visualize, and continually improve upon our beliefs as we process new information. So much of what we believe depends on what we can momentarily call to mind, but our memory is severely limited. …


2020 has been a challenging year for many and I’m sorry to report that Considdr has had to cease operations. I want to express my deep gratitude to our investors, advisors, customers, and teammates who made this project possible over the past six years. This blog will now be dedicated to preserving the company history so that the ideas we pursued might live on.

For me, this project has been a huge source of energy and purpose — something I’ve thought about and worked on virtually every day for the last six years. So more than anything, this Medium page…
