Lasting Relationships: Compatibility, Habits, and Repair
The science of lasting relationships is messier than the famous studies suggest. Innate compatibility, learned habits, and active repair each claim the starring role, and which one you believe changes how you fight for your relationship.

Sleep Training and Attachment: Evidence, Stress, and Limits
The fear that letting a baby learn to sleep damages attachment is exactly what follow-up studies were built to test, and they keep finding no harm in bonding or stress hormones. The evidence here covers how cortisol data was measured and cleaned, why parental exhaustion carries its own risks, and where the studies' limits genuinely lie. You can weigh the reassurance and the caveats together before deciding what your family needs.

Transcendental Meditation and Mindfulness: Stress, Focus, and Evidence
Transcendental Meditation and mindfulness both promise real change, but they may help different things. These claims compare where the evidence favors TM for lowering stress-related physical risk versus mindfulness for daily focus and emotional control, and where head-to-head proof runs thin. You can decide which practice fits the results you are after.

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.

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.
