著者について

『Factfulness』の著者について

Hans Rosling, acclaimed Swedish physician, statistician, and global health visionary, authored the groundbreaking nonfiction work Factfulness with his son Ola Rosling and daughter-in-law Anna Rosling Rönnlund. Published posthumously in 2018, the book challenges misconceptions about global development through data-driven insights, reflecting Rosling’s lifelong mission to combat ignorance with empirical analysis.

A professor of international health at Stockholm’s Karolinska Institute, Rosling co-founded Gapminder Foundation, revolutionizing data visualization through tools like Trendalyzer—adopted by organizations from the UN to Google. His electrifying TED Talks and viral BBC documentaries, including The Joy of Stats, made complex global trends accessible to millions.

Rosling advised world leaders from Barack Obama to Fidel Castro and received recognition in Time’s 100 Most Influential People list. Factfulness became an international bestseller, translated into 46 languages, with Bill Gates distributing free copies to college graduates. The book’s enduring legacy lies in its optimistic reframing of human progress through what Rosling called “a fact-based worldview.”

この本に関するよくある質問

Factfulness challenges the misconception that the world is getting worse by using data to show global progress in areas like poverty reduction, healthcare, and education. Hans Rosling identifies 10 cognitive biases ("dramatic instincts") that distort our worldview, such as negativity and fear, and offers strategies to adopt a fact-based perspective. The book emphasizes the importance of categorizing nations into four income levels instead of outdated "developed vs. developing" labels.

This book is ideal for policymakers, educators, students, and anyone interested in global development or data-driven decision-making. It’s particularly valuable for readers seeking to combat misinformation, reduce stress from exaggerated media narratives, and understand systemic progress.

Yes—Bill Gates called it "one of the most important books I’ve ever read." It provides actionable frameworks to reframe thinking, backed by decades of research. Readers gain tools to interpret data accurately and counter unconscious biases, making it a practical guide for personal and professional growth.

Rosling’s model divides global populations into four tiers:

  • Level 1: Extreme poverty (earning ≤ $2/day).
  • Level 2: Low income ($4–$8/day).
  • Level 3: Middle income ($16–$32/day).
  • Level 4: High income (≥ $64/day).

This framework replaces the outdated "developed vs. developing" dichotomy, highlighting nuanced economic progress.

Rosling argues instincts like negativity (overemphasizing bad news), fear (prioritizing scary scenarios), and urgency (demanding immediate action) skew perceptions. These biases lead to underestimating progress, such as ignoring the 50% drop in extreme poverty since 2000. Factfulness encourages questioning assumptions with data.

Rosling employs dynamic charts (e.g., animated bubble graphs) to illustrate trends like life expectancy vs. income over time. These visuals reveal how most countries cluster toward higher income and health levels, countering stereotypes about "static" developing nations.

Some argue the book’s optimism understates persistent challenges like climate change or inequality. Others note its 2018 data may require updates, though its core principles about cognitive biases remain widely applicable.

By recognizing dramatic instincts, individuals and organizations can avoid reactive policies, allocate resources effectively, and focus on measurable progress. For example, prioritizing vaccination programs over fear-driven responses to isolated health crises.

A Swedish physician and global health expert, Rosling co-founded Gapminder Foundation to promote data literacy. He passed away in 2017; Factfulness was completed by his son Ola and daughter-in-law Anna, blending storytelling with statistical analysis.

The book debunks myths about exponential population rise, showing birth rates stabilize as nations climb income levels. Most countries now average ≤ 2 children per woman, contradicting fears of unchecked overpopulation.

  • “The world is much better than you think.”
  • “Test your ideas with data, even if you think you’re right.”

These lines encapsulate Rosling’s call for humility, curiosity, and evidence-based thinking.

Unlike theoretical analyses, Factfulness combines personal anecdotes, accessible data, and actionable frameworks. It complements works like Enlightenment Now by Steven Pinker but focuses more on cognitive biases than historical trends.
