An Educator's Guide to Spaced and Retrieval Practice

An Educator's Guide to Spaced and Retrieval Practice

Much of what schools and parents assume about learning, including learning styles, doesn't survive testing. These strategies center on what does: spacing practice over time, recalling material instead of rereading it, and lesson designs backed by experiments. Comparing them shows where to put effort so kids actually remember what they learn.

Structured Interviews: Fairer Hiring Beyond Cultural Fit

Structured Interviews: Fairer Hiring Beyond Cultural Fit

Structured interviews with standardized questions and scoring are proven to predict job performance far better than unstructured interviews that rely on subjective cultural fit judgments. The common practice of hiring for cultural fit often masks bias and discrimination, disadvantaging diverse candidates. By focusing on objective, job-related criteria through structured interviews, employers can reduce bias and make fairer, more accurate hiring decisions.

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.

A Marketer's Playbook for Customer Testimonials That Sell

A Marketer's Playbook for Customer Testimonials That Sell

Buyers trust other customers more than they trust your marketing, but a testimonial only works if it is believable and usable. The approaches diverge on what matters most: airtight permission and legal safeguards, strategic storytelling with concrete results, third-party reviews as independent proof, or simply making it effortless for customers to say yes. Picking a lane determines whether your customer stories persuade or just decorate.
