NotebookLM: Cast with Care
Google's NotebookLM "deep dive" feature is taking off in popularity. I subject three of my academic papers to the deep dive treatment, and reveal its tendency to subvert content for a happier ending.
Lumping and splitting: brain tumours in white Britons
A much-publicised report suggests that white Britons' brain tumour survival rates are lower than other ethnicities. But analysing the ethnicities categories used, and considering the diversity of the "brain tumour" label, complicates the picture, as the 'Dismal Disease' of Glioblastoma continues to confound.
On the Global Summit: do critiques of evidence hierarchies favour chiropractic?
The Global Summit systematic review claims that spinal manipulation therapy is not effective in preventing any non-musculoskeletal disorders. But a breakaway group has challenged their findings, in part based on my arguments regarding evidence hierarchies. Are they correct? Does my critique undermine the Global Summit review? If so, does the evidence base favour chiropractic?
Minding the Gaps: Statistical Misrepresentation in Attainment Gap Research
Political interests configure the stories we tell with data. Closing the gap in attainment between disadvantaged students and their advantaged contemporaries is pivotal to an agenda to use education as a positive social force. But both the measurement and representation of this gap is politicised, skewed and open to manipulation. This paper shows how two organisations with inverse aims represent—and misrepresent—their measure of the attainment gap to portray diametric trajectories in the pursuit of equal attainment.
Conversion Therapy: Evidence is Irrelevant
Pressure mounts upon equalities minister Kemi Badenoch to resign over the UK government's failure to ban conversion therapies. Attention has focused on the government's failure to publish research commissioned in 2018. But evidence about whether conversion therapy works is irrelevant: conversion therapy is not a medical intervention.
The Dismal Disease: Temozolomide and the Interaction of Evidence
Evidence interacts. To understand the evidence base for an intervention we must look not only at individual studies, but the relationships between them.
Stop Fighting, You're Making Me SAD
Does medical science have to be adversarial to make progress? Does progress in patient care consist of weeding out treatments which are ineffective and replacing existing therapies with new and better alternatives?
The Positivity Machine: "Evidence-Based Alternative Medicine" and Grades of Recommendation
In his beat-poem Storm, the musician and comedian Tim Minchin lays out an apparent paradox. By his criteria, there can never be evidence-based alternative medicine. As soon as there’s evidence that a treatment works, it joins scientific medicine. Minchin goes on to list...
The Parachute Problem: Extracorporeal Life Support and the Demand for Trials
The United States Parachute Association recorded 120 deaths while skydiving in America in 2008-2015. Most were due to human error, while others resulted from collisions with other parachutes or aircraft. Only 5 were due to equipment failure. With around 3 million parachute...
The Avoidable Scandal: Benoxaprofen and Theories of Medical Evidence
Benoxaprofen, marketed as Opren in the UK, created a scandal in 1982 when it was withdrawn from sale amidst reports of over 60 deaths and thousands of adverse reactions. The question of who was at fault for this disaster has been addressed many times in the academic...
