Research Methodology

Our standards

Every insight page is built from established psychology and behavioral science. When we choose what to include, we favor:

• Peer-reviewed research published in recognized journals.
• Replicated findings over single, headline-grabbing studies.
• Meta-analyses and reviews, which summarize many studies, where they exist.
• Well-established frameworks — such as attachment theory, the investment model of commitment, self-determination theory, and decades of observational relationship research.

How we handle uncertainty

Psychology is full of effects that are real but small, and claims that sound confident but rest on thin evidence. We try to represent the strength of the evidence, not just its direction. That is why our language is deliberately hedged: "research suggests," "on average," "tends to," "this varies significantly." When a popular claim is weak or contested, we say so rather than repeating it for effect.

The gender-similarities principle

A guiding reference for us is Janet Hyde's gender similarities hypothesis (2005), supported by large meta-analyses, which finds that on most psychological measures men and women are far more alike than different. Real average differences exist on a handful of dimensions, but the distributions overlap heavily. We present differences where the evidence supports them, while keeping this big-picture similarity in view — so the site never slides into caricature.

Balance and tone

We cover men and women with equal depth and equal respect. We do not frame one sex as superior, more rational, or more emotional than the other. We avoid stereotyping language, sensationalism, and any framing that treats understanding as a manipulation tactic. The goal is genuine understanding, applied with empathy.

Review and dating

Each page is reviewed for accuracy, balance, and clarity before publishing, and carries a "last reviewed" date. As the field evolves or readers flag issues, we revisit and update pages. We welcome corrections — see our contact page.
