In the event that an incorrect decision group is selected during an experiment, there are a couple of approaches to address the issue.
Firstly, if the parameters on the control and test groups can be swapped without any hardcoded behavior specific to the control or test, this action could potentially resolve the problem. However, it is important to note that this may lead to corrupted data.
Alternatively, the experiment can be reset, and a decision can be made immediately thereafter. It is important to understand that resetting the experiment and making a new decision will replace the top-level results with the new iteration of the experiment, which will not contain data.
However, data from previous iterations of the experiment can still be accessed through the 'View History' feature. This allows for the preservation of historical data while addressing the issue of the incorrect decision group selection.
