LOL You're only biased if you are a Bamber supporter. Haven't you learned that simple equation yet Jan? 
No you are biased when you decide you want to believe a certian thing regarless of what the facts might be and then disregard those facts that prove your beliefs impossible instead of researhcing the facts, following the facts and making a decision based on those facts.
That is why those who beleive Jeremy is guilty can explain why and provide evidence and a rational basis for their beliefs while Jeremy supports can't provide a rational basis for their beliefs or evidence to back up their beliefs.
A perfect example is the bogus claim that Nevill phoned police. 6 people voted that they believe Nevill called police. Not one of them could provide a rational basis for such belief though. Worse yet one of them originally said it would makes no sense for Nevill to call Jeremy and then immediately call police and who cares that he didn't call police. Upon learning it would help establish Jeremy's innocence she decided to ignore her own reasoning and decide to believe Nevill called just because it would help Jeremy.
That is bias.
Ignoring that Sheila could not have shot herself without getting GSR on her hands and clothing and that she was GSR free and still insisting she did it anyway because they want Jeremy to be innocent is the result of bias.
Ignoring the moderator evidence by arguing it could have been innocently contaminated even though there is no way for innocent contamination to deposit blood on the first 8 baffles is the result of bias.
Ignoring that Sheila was receiving the optimal effective dosage of Haldol at the time of her death and suggesting it would not have worked because her dosage was cut in half is a bogu argument resoirted to because of bias.
Ignoring Sheila was not taking the countering agent to her Haldol and suggesting because her dosage was halved that means the countering agent was too high a dosage and stopped her Haldon from working is a bogus argument resorted to because of bias.
Ignoring that Jeremy lied to police by telling them Sheila could use all guns in the house and that he taught her how to use the murder weapon is because of bias.
Ignoring Jeremy was never known to shoot rabbits and that he staged too many bullets thus his tale of taking out the gun and bullets to shoot rabbits is not credible is ignored because of bias.
Pretending windows that Jeremy admitted to using to enter and exit were too spam for him o climb through is because of bias.
I can give another 40 plus examples of bias being used to ignore facts and evidence tha timplicates Jeremy.
