1/ Correction! 🚨 I found and fixed an important coding error in a chart I made. Specifically, the peach category 'lymphatic and blood cancers' in this chart wrongly included both lymphoid and blood cancers (C81-C96) plus some of its subcategories, meaning some were double-counted. Before & after:
Erroneous version of the chart with a significant share of cancer deaths being from lymphatic and blood cancers, across all ages.Fixed version of the chart with a much smaller share of cancer deaths being from lymphatic and blood cancers, especially smaller during childhood.

I want to agree but having some plan is always better than having no plan as far as analysis goes and so I don’t see the practice of registering as going out the window. I see option two with registered reports as another option to be a great balance moving forward.

The image is a humorous illustration titled “Types of Psychotherapy Research Papers.” It features a 3x3 grid of nine panels, each describing a stereotypical type of psychotherapy research paper with accompanying simplified visuals of mock text and figures. The captions in each panel are as follows:
	1.	Top left: “Oh my gosh, everything works equally well, please stop yelling.”
(Mock text with a blank rectangle in the middle.)
	2.	Top center: “We made a simple, 243-component treatment manual, but these pesky therapists won’t do it how we tell them.”
(Mock text and various line diagrams.)
	3.	Top right: “Oh my gosh, everything works equally poorly, and now I’m gonna yell about it.”
(Mock text filling the page.)
	4.	Middle left: “Ten white, middle-class adults who got a full course of gold-standard therapy felt better than ten white, middle-class adults who we ignored for 6 months.”
(Mock text with sparse lines in places.)
	5.	Middle center: “Trial of an established treatment, but with brain pictures, so now it’s real!”
(Mock text with a brain scan icon.)
	6.	Middle right: “We didn’t ask what these people want to change about their lives, but PHQ scores dropped 3 points, so treatment definitely worked.”
(Mock text and a bar graph.)
	7.	Bottom left: “Our therapy works! For the low cost of $10,000, 200 training hours, & your first-born child, you too can be a certified provider.”
(Mock text with a lot of empty space.)
	8.	Bottom center: “We made up a totally new & very unique therapy, and it is not at all a minor variation of stuff that already exists.”
(Mock text resembling a dense manuscript.)
	9.	Bottom right: “That’s great and all, but none of it matters if most people can’t access care.”
(Mock text with blank rectangles, possibly representing figures.)

This cartoon satirizes common themes and issues in psychotherapy research, such as accessibility, replicability, overcomplicated methods, and narrow study populations.
