You live in a fictional authoritarian country.
You have been accused of a very serious, vile, and stigmatising crime. You are in fact innocent and have been framed but no one believes you.
The evidence used to convict you is very strong because the third party who has framed you did a very good job; you likely would have been convicted under any system and everyone believes (reasonably) that you are guilty. The crime you have been accused of is considered serious, vile, and stigmatising worldwide.
Upon being found guilty, you are told that you can choose to either Admit Guilt ("Confess") or insist upon your innocence.
If you "Confess" you will serve 10 years in prison. However, you will be required to issue a formal and public confession that will be recorded and broadcasted nationwide to the government's satisfaction.
If you do not "Confess," you will serve 20 years in prison.
There is one more consideration:
You know that if you do not Confess, there is a 3 percent chance that after serving your 20 years your innocence will be proven and brought to the public's attention.
If you "Confess," a supernatural mechanism will instantly lower that 3 percent chance of proving your innocence post-sentence to 0 percent. In other words, you will serve your 10 years and be forever stigmatised as a very vile criminal.
In either situation, you will serve some prison time and you will be treated with a great deal of contempt and ostracisation even after you get out; the rest of your life is in all likelihood ruined (quite literally) if you aspire to something like the American Dream.
So do you Confess or do you not Confess? Please justify your decision and discuss your reasoning.
