Procedure

You can win a bonus payment of {{ Constants.bonus }} € in this study. To qualify for that bonus, you will have to make 6 trade-offs twice. Subsequently, we will ask you some questions about yourself. Finally, we will show you how much money you earned in this study.

The whole study will take about 25 minutes of your time. Reading the instructions accounts for approximately 10 minutes while the participation in the study, that is, the trade-offs as well as the questionnaire take about 15 minutes.

Each trade-off consists of two options: a bet on the weather as well as a lottery. To better assess the weather situation, you will receive information about previously measured temperatures. For the time being, you will not know anything about the location or the time the weather information refers to. After making the first 6 trade-offs, you will receive additional information. More precisely, you will be exposed to a weather forecast that you can then use to make the same 6 trade-offs once more.

Bet

We will ask you to bet on certain temperatures. You may bet that the temperature will be at least 17°C on a certain day at 14:00 (CET). If the temperature turns out to be 17°C or higher, you can earn {{ Constants.bonus }} €.

The bet corresponds to the same time and location in each of the trade-offs. The only difference between the trade-offs is the temperature interval you can bet on. As a consequence, one trade-off may consider a temperature of 17°C or more, while another trade-off involves a bet on the temperature being 8°C or less. For this reason, we advice you to carefully examine the bets' temperature intervals that can earn you the bonus.

Lottery

To better understand the lottery you can imagine an urn containing 100 colored balls. Some of the balls are colored green, the others are red. Drawing a ball randomly and blindly, you can earn {{ Constants.bonus }} € if the ball turns out to be green and nothing if the ball is red.

Trade-off

Yo have to decide unter which conditions you prefer the lottery over the bet. We'll therefore ask you how many of the abovementioned 100 balls have to be green such that you prefer the lottery.
