Scenario: you are one (1) week into organising the launch event and unfortunately there has been some friction within the team. It seems that the team members are not always communicating well and that reporting lines are not being followed. David has complained that Darren and Katrina have made some decisions on your day off that should have been run by him, as he is next-in-charge. Furthermore, there was some confusion on who was responsible for sending out invitations. Katrina is sure she remembers asking Darren to do this, whilst Darren remembers Katrina saying in the last meeting that she would do this. Finally, a budgeting issue occurred as David blindly followed your advice to go with a certain caterer who you have used for a private event and were very happy with it. He hired them without requesting a quote first, which led to an invoice that exceeded the budget. Of the list below, which barriers to critical thinking apply to this scenario (Select 3)? Trusting testimonial evidence Confirmation bias Self-serving bias Memory lapses Accepting authority without question Generalisation Ignorance/lack of humility Coincidence
