My highly scientific polls during this webinar unequivocally confirm that people working in the UK finance industry are fans of risk-dominant actions. So that's some good news for the "global games" industry.

Excited to share my JMP: "The Messenger Matters"

Does it matter who communicates policies to the public? Yes! The messenger impacts both the reach and influence of communication.
