Gut Microbiome Testing: Reliability, Regulation, and Diet Decisions
Despite popular marketing, gut microbiome tests lack FDA approval and clinical reliability, making them unsuitable for diagnosing conditions or guiding diet changes.

Power Posing and Confidence: Evidence, Replication, and Practical Limits
Power posing became a popular claim about confidence, hormones, and behavior, but later replication efforts sharply narrowed what the evidence can support. This overview explains the original findings, the methodological disputes, and the difference between measurable effects and subjective confidence. Readers will learn where posture-based confidence techniques may be useful, where the science remains weak, and how to apply such tools without overstating their power.

A Manager's Guide to Strategic Hiring, Outsourcing, and Culture
The usual outsourcing debate stops at cost, but that misses what really holds a company together.

Active Funds vs. Index Funds: Performance, Bias, and Evidence
The people paid to pick winning stocks mostly lose to a fund that simply buys everything, and it looks worse once dead funds are counted properly. The findings here differ on why: statistical bias, market efficiency, methodological blind spots, possible exceptions in bonds, and whose conflicts of interest color the analysis. Where you come down decides whether active management deserves any of your money.

Fluoride in tap water is either one of public health's great wins or mass medication without consent, depending on who you ask. These sides weigh new neurotoxicity and IQ-loss evidence, total exposure from many sources, the 0.7 mg/L level debate, and why much of Europe rejected the practice. You can weigh the science against the ethics and reach your own view.
