The Thesis
The Cognitive Transformation Gap
As algorithmic assistance becomes ubiquitous, a silent erosion of executive intuition is occurring. We call this the Cognitive Transformation Gap—the space where human nuance is traded for computational efficiency.
of executives now regularly use AI to support their decisions — without organizational structures for knowing who gets to push back.
— Mallon et al., Deloitte Insights, March 2026
Our work focuses on reinforcing the mental models required to lead when AI generates the answers, but wisdom still determines what to do with them.

About
Rigorous Insight.
Strategic Calm.
Marsh Island Group was founded on the principle that the most valuable asset for today's leaders is not more data, but the capacity to synthesize it into meaningful action.
John Koblinsky — a researcher and strategic advisor to enterprise brands including SAP, Amazon, and Microsoft — built Marsh Island to support that conviction. For twenty years he has studied consumer and professional responses to new technology, including how we form beliefs, assign trust, and make decisions as the tools around us shift.
We operate from the Pacific Northwest, drawing inspiration from the region's unique balance of technological frontierism and grounded, natural stillness.
