The activation energy framework
**The concept:** Borrowed from chemistry — activation energy is the energy barrier that must be overcome to start a reaction. For ADHD task initiation, activation energy is the executive function cost of crossing the threshold from 'considering doing X' to 'actively doing X'.
**Why ADHD activation energy is high:** Per Russell Barkley's executive function model at russellbarkley.org, ADHD brains have deficits in the prefrontal mechanisms that bridge intention → action. The bridge takes more energy AND is less reliably available. Per APA executive function research at apa.org, this is a measurable neurological difference, not laziness or character.
**The implication:** Task initiation strategies for ADHD adults work by lowering the activation energy threshold — making the start easier — rather than relying on raw willpower to overcome a higher threshold. The 7 protocols below are ranked by how much they lower the threshold.
**The diagnostic:** Notice the gap between deciding to do task X and actually starting task X. Track for one week. Most ADHD founders find their gap ranges from 5 minutes for routine tasks to 2-5 hours for high-stakes/emotionally-loaded tasks. The longer the gap, the higher the activation energy — and the more protocol value to lower it.
