The tendency to search for or interpret information in a way that confirms one's preconceptions. . . . discredit information that does not support their views. . . .
Despite reassurances from the NTSB that their long investigation wasn't "fixed",
the pilots felt otherwise about the USA's officially "independent" Safety Board.

confrontation with IIC Kampschror at the
Boeing Meeting in Seattle for the flight test.
[The IIC later excluded this letter from the NTSB's docket.]
Lessons from the Boeing-led
Night FL390 CRZ Yaw x Roll = DIVE
B727 N840TW, TWA 841 4Apr'79
The manufacturer stacked-the-deck:
to call-out against the cards-dealt,
and too awed to reject the erroneous Boeing Scenario.
Masses of data, from "simulator trials" and from an Oct'80 Flight Test,
with selective data-dredging by Boeing engineers,
swamped the Safety Board's struggling staff-engineers:
Staff investigators thus looked-past the direct evidence
(Wreckage Examination, Trail of Debris, pilots' testimony, mishap-FDR-data),
instead glorifying data fabricated after the accident
at manufacturer's facilities.
