The disconnect has been there all along. There is a continuity which represents the likelihood that a particular feature is artificial or not. Mt. Rushmore would fall and the end of the scale that respresents 100% certainty of artificiality. An impact crater would fall at the other end of the scale. The closer one gets to either end of the scale the more objective the determination can be. Unfortunately, there is a section in between where objective truth gives way to the subjective and indeterminate. To some, the Face falls near the objectively artificial end of the scale. To others, like myself, it is well within the subjective, indeterminate portion. Frankly, I have a difficult time seeing a face in the 1998 image at all. I'm not sure that I would even see as much as I do if not for the 1976 image. That indicates to me that my perception of the 1998 image is biased by the 1976 image. I think this is a good argument for the position that the images are well into the subjective, indeterminate part of the scale. Better images of the Face may expose features that for people like me move it closer to the artificial end of the scale, but it is also possible that it will remain indeterminate. My position is such that better images may move me in any direction. Your position is that, like Mt. Rushmore, it appears to resemble a humanoid face to such a high degree that absent any evidence to the contrary it must be assumed to be artificial.
On the subject of your sucessful hypothesis predictions and their relevence, if the 1976 image had not been noticed (until after the 1998 image) and the face was not discovered until the 1998 image, would the fact that no hypothesis was held and no predictions made and passed have had any effect on your determination, based only on the visual evidence in the images, that the face is artificial? If you answer no, then exactly what was the value of the predictions if they added no weight to the notion of artificiality? If you answer yes, then you must admit that the success of your predictions has influenced (biased?) your interpretation of the 1998 image. I will have more to say on this later.

Evidence and data which agrees with (and bears out) previous predictions are immeasurably more significant than original data observed at random. So the "effect on your determination" should be enormous.
<i>and also</i>: "If you answer yes, then you must admit that the success of your predictions has influenced (biased?) your interpretation of the 1998 image."
The main problem with your conclusion here is that "influence" and "bias" are not the same thing. An <i>a priori </i>prediction that is successfully made is not a "bias" because there are now good logical and empirical reasons for an increased confidence in one's conclusion (in this case the artificiality hypothesis). Whereas a biased opinion does not change, notwithstanding evidence pro or con. So a conclusion or "influence" can be based on sound reasoning or it can be the result of predjudice (bias).

So he set up an <i>a priori</i> test: If natural, then when future images reveal what's to the right of the strip, it will be plain sand, craters, hills, mesas, irregular lava flows, or countless other natural landforms. But if artificial, the landform will be very specific -- the completion of the animals hind quarters, missing leg, and a tail of the right proportions, uniform shape, orientation, and location with respect to the animal's body.

Hey Tom?
Hasn't this test already been done? I recall seeing somewhere (forgot where) the rest of the contested area. I just can't remember if it was a new MGS photo or an artists scetch of what the new area *might* look like.

Tom, I truly hope that the MRO can provide proof either way, but my own **prediction** is that the Face is inherently visually ambiguous at any resolution and this will remain unsettled for a very long time.

If my subjective interpretation of the gross features is in such variance with yours, why should I place any confidence in your subjective identification of the existence of the predicted detailed features. If the tests aren't objective, then they don't support the predictions as claimed.

The first instance of any statistical anomaly can always be a fluke, and can only be used to formulate hypotheses for testing.

Doesn't that defeat the whole purpose of finding an objective test whose outcome the experimenters and viewers cannot influence?

Here's another example of its application. In 2001, JP Levasseur found this image (left) in an MGS photo, and wondered if it was natural or perhaps another example of flat art, a puma-like animal, as in this key (right):
So he set up an <i>a priori</i> test: If natural, then when future images reveal what's to the right of the strip, it will be plain sand, craters, hills, mesas, irregular lava flows, or countless other natural landforms. But if artificial, the landform will be very specific -- the completion of the animals hind quarters, missing leg, and a tail of the right proportions, uniform shape, orientation, and location with respect to the animal's body. Do you agree that, when the new data is seen, this will be a good test?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">I think you can guess what I think of the *flat art* phenomena.

Tom, I truly hope that the MRO can provide proof either way, but my own **prediction** is that the Face is inherently visually ambiguous at any resolution and this will remain unsettled for a very long time.

I don't believe that someone like jrich, who appears to be an educated person, is ever going to be convinced by logical arguments, let alone scientific ones. He seems to be saying that if we can not attain some absolute degree of certainty that there is no hope of ever gaining any real knowledge of artificiality (in this case of the Face at Cydonia).
If I read Tom right, he is saying that the objective tests are scientifically preferable (indeed necessary) over intuitive statements that such and such a face looks "artificial" as opposed to "natural." And for the purpose of proposing any viable scientific theory that will be taken seriously by the scientific community he is right.
Even after such objective tests are made and the results are positive, one still needs to go through the process of verification, and confirmation, whether on the ground, or by better imaging, spectroscopic readings, or whatever. Why? because even objective tests don't give us the degree of certainty required to know for certain.
I get the distinct impression that jrich is not really arguing science, but epistemology. How do we know what we know?
