Bitcoin for learning, market share meaninglessness, and fighting poverty with evidence.

College diploma

1. Bitcoin tech records people's learning.
Ten years from now, what if you could evaluate a job candidate by reviewing their learning ledger, a blockchain-administered record of their learning transactions - from courses they took, books they read, or work projects they completed? And what if you could see their work product (papers etc.) rather than just their transcript and grades? Would that be more relevant and useful than knowing what college degree they had?

This is the idea behind Learning is Earning 2026, a future system that would reward any kind of learning. The EduBlocks Ledger would use the same blockchain technology that runs Bitcoin. Anyone could award these blocks to anyone else. As explained by Marketplace Morning Report, the Institute for the Future is developing the EduBlocks concept.

 

Market share MIT-Sloan

2. Is market share a valuable metric?
Only in certain cases is market share an important metric for figuring out how to make more profits. Neil T. Bendle and Charan K. Bagga explain in the MIT Sloan Management Review that Popular marketing metrics, including market share, are regularly misunderstood and misused.

Well-known research in the 1970s suggested a link between market share and ROI. But now most evidence shows it's a correlational relationship, not causal.

 

Adolescent crime

3. Evidence-based ways to close gaps in crime, poverty, education.
The Laura and John Arnold Foundation launched a $15 million Moving the Needle Competition, which will fund state and local governments and nonprofits implementing highly effective ways to address poverty, education, and crime. The competition is recognized as a key evidence-based initiative in White House communications about My Brother’s Keeper, a federal effort to address persistent opportunity gaps.

Around 250 communities have responded to the My Brother’s Keeper Community Challenge with $600+ million in private sector and philanthropic grants, plus $1 billion in low-interest financing. Efforts include registering 90% of Detroit's 4-year-olds in preschool, private-sector “MBK STEM + Entrepreneurship” commitments, and a Summit on Preventing Youth Violence.

Here's hoping these initiatives are evaluated rigorously, and the ones demonstrating evidence of good or promising outcomes are continued.

 

Eddie Izzard

4. Everyday health evidence.
Evidence for Everyday Health Choices is a new series by @UKCochraneCentr, offering quick rundowns of the systematic reviews on a pertinent topic. @SarahChapman30 leads the effort. Nice recent example inspired by Eddie Izzard: Evidence on stretching and other techniques to improve marathon performance and recovery: Running marathons Izzard enough: what can help?

5. Short Science = Understandable Science.
Short Science allows people to publish summaries of research papers; they're voted on and ranked until the best/most accessible summary has been identified. The goal is to make seminal ideas in science accessible to the people who want to understand them. Anyone can write a summary of any paper in the Short Science database.
