The claim that Mozart’s music, and the sonata K448 in particular, reduces epileptic activity got a wide hearing and made its way into medical advice. To test it, eight studies were pooled and run through many combinations of analysis decisions, a . What survived?
Nothing stable. Across 207 participants the overall result was small and not significant, and the large effects came from a few . Which is to say the finding is not robust across the ways it could be analyzed, and that is exactly the weakness the method is designed to expose.
began as a claim about a spatial test, and the medical version, that a particular piece reduces epileptic activity, is far stronger than a claim about improving mood: it requires a mechanism.
The researchers pooled eight studies with two hundred and seven participants, and ran the analysis in many combinations of defensible decisions, instead of choosing one path and presenting it.
The overall result was small and not significant, and the large effects came from a few outlying points. Which is to say the finding is not stable across the ways it could be analyzed, and that is exactly the weakness the method exists to expose.
Further studies were left out as : they reported too little and their authors did not provide it, and that uncertainty stays open. A pleasant piece of music can help how somebody feels, and it is not a proven treatment for epilepsy. Only eight small studies were included, and a later review read the literature more favorably.
wat. Eight studies on Mozart and epilepsy gave no stable evidence for an effect specific to the sonata K448.

A pleasant piece of music can help how somebody feels, and it is not a proven treatment for epilepsy.
How do we know?
A multiverse meta-analysis tested the finding under many analysis options, instead of choosing one path and reporting it.
What is still unknown
Only eight small studies were included, and a later review read the literature more favorably.
