Episode

In a world where we are constantly bombarded with requests for our time and money, how do we actually decide to be generous? In this episode, I sit down with Cherian Koshy, VP at Kindsight and author of NeuroGiving: The Science of Donor Decision Making, to explore the fascinating intersection of behavioral science, philanthropy, and predictive modeling.

Beyond the "Hard Sell": Fundraising as Belief Updating

One of the most provocative shifts Koshy suggests is moving away from the idea of persuasion. He argues that fundraising should not be a hard sell, or an attempt to push someone into caring. Instead, he views it through a Bayesian lens as belief updating.

People generally already care about causes and see themselves as generous. The real question for nonprofits is: Under what conditions does generosity align with the identity that people already want to live out? When a donor interacts with an organization, they aren't just making an economic choice; they are making a cognitive and identity-based decision. Every interaction serves as evidence that either reinforces or contradicts their existing priors about their own identity and the organization's trustworthiness.

The Paradox of the Generosity Gap

The episode dives into a concerning trend known as the generosity gap: while total donation amounts are increasing, the actual number of individual donors is declining. This suggests that generosity is concentrating among a smaller group of committed donors with strong, positive trust priors.

To bridge this gap, Koshy suggests that organizations must focus on:

• Building trust biologically: Trust is not just squishy; it's a biological process involving oxytocin and reward systems.

• Micro-engagement: Much like starting a fitness routine with one pull-up a day, donors need micro-doses of engagement to build momentum and update their trust priors over time.

• Eliminating friction: Many organizations accidentally sabotage themselves with complicated donation forms. These shift the donor’s brain from generosity mode into risk assessment mode, leading to high rates of cart abandonment.

The Role of Ethical AI

As AI becomes more prevalent in the nonprofit sector, Koshy warns against using it purely as an extraction engine to maximize short-term revenue. While algorithms can predict who is likely to give based on emotional triggers, doing so can undercut long-term trust.

Instead, ethical AI should be used to help institutions remember donors better. By using AI to track and reflect a donor's interests and history, organizations can build a trust history that transforms a transactional relationship into a meaningful, long-term alignment.

Generosity as "The New Green Juice"

Perhaps the most compelling takeaway is that generosity is hardwired into our biology. Acts of giving activate the brain’s reward systems and social bonding chemistry, producing dopamine and oxytocin. Research indicates that being generous can lower stress levels and provide health benefits comparable to quitting smoking.

Ultimately, generosity is the invisible infrastructure of our communities. When we align our actions with our identity as generous people, we don't just help a cause -- we become our best selves.

Hope you enjoyed, and see you in two weeks, my dear Bayesians!
