If you vanished from your job tomorrow, what would change? When is a high paying job more impact than direct service? How do you estimate your counterfactual contribution without fooling yourself? What signals tell you a problem is neglected rather than merely unpopular? Are you optimizing for visible outcomes instead of real outcomes? Which incentives in charities and NGOs quietly distort priorities? Could a simple weighted factor model outperform your gut on big choices? What would make you switch paths even if you feel committed? How do you balance personal fit with moral urgency?

What does personality capture beyond momentary behavior, and how do traits differ from life specific adaptations? How stable are traits across the lifespan when we separate rank order from mean level change? Can psychotherapy shift core traits like neuroticism or mainly improve functioning at the same level? How much of behavior is the person, the situation, or their interaction, and how do traits shape the environments we end up in? What trade offs come with being high or low on extroversion, conscientiousness, agreeableness, openness, and neuroticism? Why do people high in neuroticism both perceive more stress and land in more stressful situations? Which life events reliably nudge traits and why do the same events push different people in opposite directions? When should we replace categorical diagnoses with dimensional spectra that align with the Big Five and guide unified treatments?

What would a global ban on industrial animal agriculture by 2050 actually achieve across welfare public health and climate? Can a phased transition built on price taste and convenience overcome identity, culture, and religion in shaping diets? Which mix of informational, financial, and regulatory policies shifts behavior without backlash? Where is the line between small humane farms that persist and large systems that must end? How do we align consumer values with daily choices when cognitive dissonance makes the topic uncomfortable? When does a little guilt motivate change and when does it harden resistance? What evidence would show that plant-based and cultivated options have reached parity that tips the market? How do we protect farmers and workers while shrinking harmful production at scale? What are the realistic tipping points for social norms around meat in different communities? If the expected suffering avoided each year dwarfs human history how should that reshape priorities?

What is the core public interest case for foreign aid beyond soft power? How should we define safety and prosperity? Why do many voters believe aid is a quarter of the budget when it is a tiny fraction and how does that shape support? How did a political decision to halt awards ripple through real programs and what safeguards failed? What legal and institutional checks should prevent a single administration from impounding funds that Congress appropriated? When government pauses, how can private funders triage the most life saving pieces without letting systems collapse? If an agency is rebuilt, which programs should be protected first and which processes should be redesigned from day one? How do we embed evidence and cost effectiveness at the start of strategy rather than as an afterthought in evaluation? What would it look like to center partner governments in the process so that learning becomes part of their own delivery? How can we avoid a fixation on what is easy to measure while still demanding clear estimates and accountability? What does it mean to meet donors where they are while steering them toward the highest impact use of funds?

How can we distinguish “real CBT” from supportive talk - does it include homework, clear goals, or a manualized plan? When therapy “doesn’t work,” is it the modality, the match, or weak training? Are common factors enough once symptoms disrupt daily life? Why does fragmented care push patients to choose meds or therapy by luck of first contact? When are meds a useful boost versus a detour from solving life problems? What’s distinct about DBT—skills, validation, and balancing change with acceptance? How does radical acceptance cut suffering without excusing harm? Which skills travel across diagnoses? How do we prevent therapist burnout and drift from the model? If we want durable gains, should we favor therapies that teach skills we keep after treatment ends?
