Text stimulus (diagram): Two-axis matrix. Horizontal axis label: "Audience size" with "Small" on the left and "Large" on the right. Vertical axis label: "Identity linkage" with "Low" at the bottom and "High" at the top. Blank area: all four quadrants blank with light grid lines and no plotted examples. The matrix has audience size from small to large and identity linkage from low to high. Where would a verified public portfolio fit?
