A single sugar sachet of lead dust spread over a football field is enough to cause lead poisoning. This potent toxicity is non-intuitive to manufacturers who perceive adding 1% lead to paint as just 'a splash,' underestimating the severe public health risk.
An intervention in India found that identifying and recruiting community influencers—people most likely to spread news of a local fair—as "immunization ambassadors" was far more effective at increasing vaccination rates than standard SMS reminders. This harnesses existing social networks for public health goals.
Karen Levy argues that making sustainability a prerequisite for funding can be a moral failure. It's like refusing to save a drowning child today because you don't have a plan to save all future drowning children. This mindset distracts from immediate, high-impact opportunities.
The standard patent system, which rewards innovation through high prices, is inefficient for creating products for the poor like vaccines. Advanced Market Commitments (AMCs) solve this by creating a pull mechanism: a legally binding promise to buy a large quantity at a set price, guaranteeing a market and aligning incentives for innovation.
In joint households in Uttar Pradesh, the wife of a younger brother has a lower social rank, leading to her being underweight from doing more work and eating last. This directly results in higher rates of neonatal mortality and stunting for her children, even when controlling for other factors.
Because genetically engineered organisms like mosquitoes with gene drives will inevitably cross borders, their deployment cannot be a unilateral decision. Malaria expert James Tabenderana argues that it requires a regional governance framework and consensus from bodies like the African Union, making the political challenge as significant as the technical one.
Sarah Eustace Guthrie explains that charities are structurally prone to ineffectiveness because they lack the direct feedback loop of a business. A business fails when consumers stop buying a bad product. A charity can continue receiving donor funds for an intervention beneficiaries don't value, as the donor, not the recipient, controls the money.
Data scientist Hannah Ritchie points out that major agrochemical companies often don't categorize Sub-Saharan Africa as a distinct region, lumping it in with Europe for reporting. This signifies a lack of commercial interest, which stifles investment in locally-adapted seed varieties and fertilizers, perpetuating low agricultural productivity and poverty.
To combat the bias of wanting to continue a program even when results are disappointing, Karen Levy advocates for "pre-policy plans." This involves getting all stakeholders (e.g., government, researchers) to agree in advance on the specific actions they will take based on different potential study outcomes, ensuring evidence-based decisions are made.
Malaria expert James Tabenderana notes that research is adopted much faster when led by national researchers. In the Sahel, studies on malaria chemoprevention were quickly implemented because local researchers, with their existing trust and relationships with ministry of health officials, could effectively bridge the gap between evidence and policy.
Rachel Glenister argues that the best Randomized Control Trials (RCTs) are not those that simply test if a specific program works, especially if it's logistically complex and unscalable. Instead, the most valuable RCTs test a more fundamental, generalizable theory about human behavior, yielding insights that can be applied across many contexts.
The infamous PlayPumps failure was worse than commonly understood. The charity often replaced functional, simple hand pumps with their complex, expensive, and frequently broken play structures. This left communities with less reliable access to water, representing a net loss funded by major organizations like USAID who failed to do basic due diligence.
The Lead Exposure Elimination Project's story reveals a potential weakness in GiveWell's model. Its preference for proven, repeatable interventions can lead it to decline funding for more uncertain but potentially higher-impact "hits-based" approaches like policy reform, which Open Philanthropy, with its different risk tolerance, was able to support.
Alexander Berger argues that even by long-termist standards, "near-termist" work in global health is valuable. It builds crucial infrastructure—like policy advocacy experience, trusted grantee relationships, and feedback loops on what works—that can later be leveraged for long-termist goals like biosecurity, creating optionality and reducing risk for the overall portfolio.
Lucia Coulter found that the paint industry isn't always resistant to regulation banning lead. Some companies want to switch to lead-free alternatives but fear being undercut by competitors who don't. Enforced, industry-wide regulation creates a level playing field, making them supportive of the government's intervention. This dynamic makes policy change more tractable.
