Primary Outcomes (explanation)
Primary outcome variables are POST_OO and delta_OO:
1) POST_OO = number of clicks on the opt-out option after treatment induction (task 2), being a proxy of effort respectively shirking for each individual i, directly observed
2) PRE_OO = number of clicks on the opt-out option in the pre-treatment stage (task 1), a proxy of effort respectively shirking for each individual i, directly observed
3) delta_OO = POST_OO - PRE_OO representing the difference in shirking frequency between post-treatment and pre-treatment stage, for each individual i, constructed
