In our tasks you will be asked to make decisions, e.g., choose between two lotteries, how much of a budget to invest into something, etc. At the beginning of most task you will be endowed with some money. Whenever you are asked to invest or pay something, this will be deducted from the money you got up front. All tasks are designed in such a way that you will never owe us some money. The worst that can happen to you is that you lose all the money that you received at the start, but this will not happen very often if you take your decisions carefully. In some tasks there will be an element of chance. For example, the GXP computer may randomly determine a partner for you to play with or randomly draw one of several of your decisions to pay them out. You will always be truthfully informed about the consequences before you take a decision. The tasks do not take much time and their approximate duration will be indicated before you start the task.
Sometimes the consequences of your decisions will depend on what other participants decide. You will be informed before you start the task whether the consequences of your decision depend on the decisions of other participants. If you are participating in a group task, you may be asked to wait until all members of your group are online, or until other members of your group have made their decision.
