What is the meaning of the word "reckless disregard" in the context of a claim of intentional disregard?

29 The court there discussed the applicable semantics in United States v. Egenberg, 441 F.2d 441, 444 (CA 2), cert. denied, 404 U.S. 994, 92 S.Ct. 530, 30 L.Ed.2d 546 (1971), and noted that the defendant there had acted with "reckless disregard" of whether the statement was true "or" that defendant had acted with a conscious purpose to avoid learning the truth. In United States v. Abrams, 427 F.2d 86, 91 (CA 2), cert. denied, 400 U.S. 832, 91 S.Ct. 64, 27 L.Ed.2d 63 (1970), the defendant had acted with reckless disregard of whether the statements made were true "and" with a conscious purpose to avoid learning the truth. Compare United States v. Gentile, 530 F.2d 461, 471 (CA 2), cert. denied, 426 U.S. 936, 96 S.Ct. 2651, 49 L.Ed.2d 388 (1976), which approved the use of "deliberate disregard" rather than "reckless disregard" in the particular here under consideration.
