The scenarios (selected from Knutson et al. [2010] and translated to Czech) will be displayed at a speed of 65 ms per letter and additional 350 ms after each line, which should result in a normal reading speed. After the whole description of a situation is shown in this way, participants will answer a question: “Do you think that the described behavior was morally wrong?” using two buttons: Yes and No. Afterwards, they will move to the next scenario. After judging all scenarios, participants will be informed that they will read the descriptions once again, they will see their previous answers and they will be asked: “Select on a scale to what degree was your initial evaluation of the behavior intuitive or rational.” They will be also given an opportunity to change their initial judgment by a prompt: “If you want to change your original evaluation after the second reading of its description, check this box:” After going through all scenarios for the second time, participants will be asked: “If you feel you had trouble understanding or following the instructions or were not focused during the experiment, we probably should not use your data. Do you believe we should use your answers in our study?” Afterwards, they will be asked: “Did you notice anything unexpected during the experiment?”. In case they answer “Yes”, we will follow up with an open ended question: “What did you notice?”. Next we will ask them whether they know, what does the term choice blindness mean and if yes, we will ask them to describe it briefly. Then we will show them how some of their initial answers were manipulated and ask them whether they had noticed such manipulations. Finally, participants will be asked: “Did you know design/goal of the study? (e.g. because previous participants had told you about it) <br> References Knutson, K.
