The Left-Brain Right-Brain Myth: Evidence from Modern Neuroscience

The idea that logical people run on the left hemisphere and creatives on the right has sold countless personality tests, and brain science does not back it. The arguments here take the myth apart from different directions: imaging that shows both hemispheres working together, the wiring of brain networks, individual variability, and rigorous method. What remains is a more interesting picture of how your brain actually divides its work.

Trauma Therapy Evidence: Separating Body Memory Claims from Science

Trauma Therapy Evidence: Separating Body Memory Claims from Science

Many popular claims about trauma therapy based on The Body Keeps the Score rely on limited or promotional sources rather than solid scientific evidence. This leads to confusion between compelling body-memory ideas and the actual, often inconclusive, research on trauma treatment effectiveness. Recognizing these gaps helps avoid uncritical acceptance and encourages demand for rigorous data that can truly improve trauma therapy outcomes.

Studying Lasting Love: Evidence, Methods, and Limits

Studying Lasting Love: Evidence, Methods, and Limits

Studying love scientifically forces awkward choices about what counts as evidence. The methods here span controlled experiments chasing cause and effect, frame-by-frame observation turned into math, deep single-case studies, and models that treat couples as constantly shifting systems, with some researchers insisting there are hard limits on what any of it can know. Where you land shapes which relationship advice you take seriously.

You can weigh the reassurance and the caveats together before deciding what your family needs.
