Down to the wire...

May 06, 2026

Dear Trial By Error Supporter--

This is the final stretch of what I expect to be the last of these Berkeley crowdfunders. With a mini-surge in the last couple of days, the campaign has reached 81% of the goal, so the end is in sight. The crowdfunding has been the least favorite part of this project, but the support I have always received has been amazing. 

If you'd like to donate this time around, here's the link:

A new interview...

May 04, 2026

recently published paper reported that incidence of ME/CFS peaks in adolescence and in early middle-age.  I spoke with senior author Audrey Ryback, an immunologist at the U of Edinburgh, about the findings and what they might mean. The interview is here.

If you'd like to support the current crowdfunding campaign, now's a good time! Here's the link:

It's DONATION FRIDAY!!!

April 30, 2026

I try to find something interesting and/or entertaining to say in these messages, but sometimes I can't come up with anything particularly compelling. (It's getting to that time in the campaign.) 

The campaign is closing in on 400 donations, which is pretty good, and has reached 58% of the goal, which isn't quite as good. If you're in the mood to celebrate Donation Friday with a gift, here's the link:

Offering a good return on investment through December, 2026...

April 27, 2026

As I have mentioned, I'm planning to retire from Berkeley at the end of this year. Unless something changes, that means this crowdfunding campaign, which provides support for my academic position from July through December, will be the last one. 

I have done my best to provide a good return on investment since I began crowdfunding on Berkeley's platform in 2018, and I plan to keep doing that through December. I am amazed at the support I've received over the years. If you'd like to help keep me going for this final round, here's the link:

Two weeks left in Trial By Error's spring '26 crowdfunder...

April 21, 2026

The current campaign has been off to a slow start, but it has just passed 200 donations!!! Hopefully things will pick up a bit in the second half. I'm looking forward to spending the rest of the year continuing to do what I've been doing since I published my PACE investigation in 2015--pushing back against harmful science. 

If you'd like to support me in that effort, here's the link:

Thanks to all past, present and upcoming donors!!--David

Slow start to Berkeley's last campaign for Trial By Error

April 08, 2026

After the first couple of days, the crowdfunder is at 2% of the goal--a slower start than usual. It's not a good idea to start a crowdfunder during a war!

Spring 2026 campaign has launched--

April 06, 2026

Dear Trial By Error Supporter--

(Please ignore prior e-mail-the link didn't function.)

I am planning to retire from UC Berkeley at the end of this year. (I will be 70 in October.) That means this crowdfunding campaign will be the last one for this iteration of Trial By Error, since it will cover my position from July 1 through December 31. (My next steps are not yet clear; I could continue the project in some form. I just don't know.)

Thanks so much for your past support. You will receive a batch of these reminders over the next few weeks. (Sorry about that!) 

If you'd like to support my work this time around, you can donate to the current campaign here: https://crowdfund.berkeley.edu/project/49720

Thanks for contributing to another six month of Trial By Error...!

November 28, 2025

The crowdfunding campaign ended up slightly surpassing the goal, with 568 donations. I took a couple of weeks off and am now back working again. Most recently, I have posted a blog about yet another Long COVID exercise study touting clinically insignificant findings as evidence of benefit and one about a new cookbook for people with chronic illness.

Thanks again!!--David
