Whether or not to do

However, such findings should be treated with caution, because the participants of most of these studies were instructed to tell a falsehood without having a choice about whether or not to do so.

然而，对类似的研究结果应该慎重对待，因为每一个受试人员是被引导说谎却无权选择做于不做。

The first thing every bank will do is study how much money I have and how much debt I have before they decide whether or not to lend me any more money.

每个银行要做的第一件事就是研究我有多少钱，我有多少债务，然后再决定是否再借钱给我。

After all, it's hard to do a double-blind test when the subjects can see for themselves whether or not the light is on.

毕竟，要做双盲测试是很困难的，因为受试者自己可以看到灯是否亮着。
