You seem to cherish the notion that, "dimension", is a philosophical term, rather than its "definition #1", which is entirely in the physical realm.
Again, I did not mean to insult nor did I mean to denigrate your post. It was a comment about thinking about the negative results from SETI maybe not being due to changing RF use and not about dimensions. The term "2D thinking" is a reference to pop culture from the Star Trek movie, "The Wrath of Khan". In the movie, Mr. Spock is speaking to Capt Kirk about how the attacks Khan is making on the Enterprise seem to originate and are expressed.
"1D thinking" is linear. A to B. I prefer it. The ship is there, shoot it. The point is this. Self-evident being the key. All the readers understand and agree to the terms being used. In the article, experimenting on humans is bad. Period.
"2D thinking" is predator thinking (trying to relate to this). The prey is there. If I attack the prey it will see me, therefore I go behind the prey and attack. (See the movie clip).
"3D thinking" is spatial, vector forces, statistical, influences, cultural (I'm running out of common core of language references), . When the commenters talk about 'other factors' such as 'greater good', 'other useful results', they're talking about results outside the dimensions of the experiment. I used to think that 'metadata' was 4D thinking but have revised that conclusion to retain it in 3D cognition, just that the observer has changed and is writing down to the reader's comprehension limitations.
"4D thinking" is path thinking but 'grokking a fullness'. Does age and size of the trees affect the size of the prey? Are there non-linear non-direct vector influences on the results. Dark matter, dark energy is an example. The rules say this. This is not happening. Another factor is influencing. Describe it. 4D thinking is fraught with logical fallacy and thinker error traps. Using 4D thinking and the resultant non-linear vectors I can show that HIV was caused by Presidents Kennedy and Lyndon Johnson and Hitler and Mussolini each following the paths they took and likely would not have happened without all of them.
I only wound up mentioning SETI as a side issue when discussing CRISPR when it was a 'new technology' because of the dangers of CRISPR. Sadly, these Chinese scientists were caught human experimenting. I do not doubt that there are others around the world and the US who have not been caught. I responded your post, half in jest, because I've recently assembled a Linux Mint Cinnamon MSI 3600 system and spent some time getting SETI to run on it. Not yet as simple as Windows 7. Reading the continuing posts about needing money and equipment (and today storage) reminded me of the early days, then and now, still begging for resources. The irony is that the SETI shared computing methodology is the basis for basic research on numerous sciences around the world from protein folding to cryptocurrency. In a larger metaphor, I see the penniless inventor while better salesmen get rich.
Everything you've said about science is true. From your past posts, I'm quite sure you understand them clearly. What I tried to point out, and apparently did a poor job of it, is that, in spite of the science and the math, people do win the lottery. SETI is a very very long shot lottery. As our RF to digital RF history shows, it won't be a simple 1924 Olympic Games broadcast discovery. The last I heard, there are people at SETI evolving that thinking. I'm a long shot bettor. We'll see how that turns out.
