Before a polygraph can be performed, the test-giver asks a series of questions to which he knows the answers to ascertain a baseline. Therefore, when a lie is given, it's clear because the needle spikes amidst the truth. Everyone has a different baseline, and some people can BS the lie detector, but it's a rare one who can.
The reason I'm giving you a brief lesson in polygraphy is because what I see across the board in the blogosphere is a lot of people citing spikes as norms (on every side in every issue)—and it's not helpful.
I think if we were to more often consider a holistic picture of any movement (political, spiritual, etc.) we would not only find a more holistic argument for their views—founded or not—and, which is more, we would find people. We would find individuals who care deeply about their issues and often times have deeply personal reasons for caring about them. I'm not arguing that every position should be considered viable, but every person ought to be considered, particularly by Christians, whose ministry is one of reconciliation—namely the reconciliation of man to God.
Recently I've been cited as being part of the Young Restless Reformed corner of the Church. True or not is beside the point (if you have a problem with that, reread the former paragraph). One common pushback on the YRR is that they only listen to like-minded individuals and only call out in public those who disagree. However, if you, like the polygraph giver, would observe the baseline truths of what God is doing there, you'd find they're actively involved in calling out their own brothers and sisters where error occurs. I know my email inbox has been filled with an equal amount of caution and encouragement—and I'm fully prepared for more public responses as my readership grows.
A perfect example of good discourse on this currently is the current amiable conversation between Thabiti Anyabwile and Doug Wilson—on a very polarizing issue—on their blogs. It's been a pleasure to watch a disagreement play out between brothers with good-will and gospel focus.
If you find yourself citing spikes and rushing to share the latest drama from any particular corner of the internet, a word of caution: establish a baseline first; find every reason to think the very best of individuals you're planning on slandering or sharing information about, and then press near to the Holy Spirit for He ushers us into all truth (Jn. 14:26)
(This actually wasn't written in response to the accusations leveled at me from the former post, just thoughts that have been rolling around in my noggin for a while.)
