Jane Klein covers the science of why our phones are so hard to put down. She has a research background in behavioral neuroscience and writes for readers who want more than headlines about cortisol and dopamine. Her articles examine variable-reward systems, attention economy mechanics, short-form video effects on cognition, and the design choices that make modern apps feel like slot machines. When studies disagree, she says so. When the evidence is thin, she labels it.
