Decomposition of Inquiries Sent. The figure shows the number of inquiries sent split by the number of suggested links (light and dark orange) and non-suggested links (light and dark gray) in baseline and nudging sessions as a function of the number of rounds played. The lighter areas (both orange and gray) depict bi-directional links, whereas the darker areas (both orange and gray) depict unidirectional links. The dashed black line depicts the center between the last round in which suggestions are active (round 5) and the first round in which they are removed (round 6)
