[__ Science __ ] Subjective (Bayesian) Probability

Step 1:

When there is no clear binary (yes or no) answer to an issue, I automatically resort to probabilistic reasoning by weighing the evidence. This process is dynamic. As I learn more evidence, my opinion may change dynamically. I almost never refute anything 100%; I weigh every piece of evidence. E.g., What is the probability that the Shroud of Turin shows the image of Jesus?.

Let proposition P1 = The Shroud of Turin shows the image of Jesus.
P2 = The Shroud of Turin does not show the image of Jesus.

Between 0 and 10, how much weight do I put on each of the above propositions?

For P1, I assign 7; P2, 3.

Once I have assigned a weight to a proposition, how can anyone tell that I didn't just do it arbitrarily or whimsically?

Luckily, there is a mathematically sound answer to this question.

That's Step 2:

After a probability (or weight) is assigned, there is a scientific way to assess one's weighting scheme.

The strength of my subjective beliefs can be measured objectively as the process of wagering based on probabilities/weights. My personal belief system should be coherent even if it is subjective. In general, you can use the Bayes rule to make any decision optimally in life. In practice, the better you estimate the three input probabilities, the better your decision.

Are we to estimate the probability, which would only make it a majority rule guess or should we Spiritually discern that which we hear as there is no deciphering as that would only be a carnal mind understanding that gives no place for the Holy Spirit that teaches us all truths, John 14:26.

Rom 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace.
Rom 8:7 Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
Rom 8:8 So then they that are in the flesh cannot please God.
Rom 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.

To try and understand you better can you tell us of your religious affiliation, what Church you attend, Thank you.
