You are a Director at SkyGames, a leading gaming software technology company. Your team is tasked with making a crucial decision regarding a major investment in a new product line. Before the group discussion, individual members had differing opinions about the level of risk associated with this product investment. Some believed it was a high-risk venture, while a few others thought it was relatively low-risk. After a lengthy and comprehensive group discussion, the majority of the team members have shifted their stance and now strongly believe the investment is low risk. This shift can be attributed to:

The diffusion of decision responsibility among group members
Group member diversity
Group polarization
The risky shift phenomenon
