Bullshit: (1) Data (often a firehose) produced by someone who is indifferent to the truth or falsity of what is being said (my short version of of Harry Frankfurt’s definition in On Bullshit. See also, the Wikipedia summary). (2) Data that appears to contain more information than it actually does (my version, which I think is roughly equivalent). (3) Noise randomly tagged with truth-values to give it apparent legibility (4) Non-requisite variety
Gollumization: The impoverishment of a system through ephmeralization and weaponized attention.
Ephemeralization: The natural conversion of signal into bullshit through creative destruction (derived from original definition due to Buckminister Fuller).
Arbitrage: Exploiting bullshit for profit.
Weaponization: Separation of data into information and bullshit, and deliberate direction of the two signals at different systems (generally a hunting party and a cargo cult respectively), with the intention of creating serendipity in one system and zemblanity in another.
