has "deem" been used correctly?

[alpacinou]

Hello.

Has "deem" been used correctly in this sentence:

High consumption of energy is deemed as one of downsides of this new machine.

 

[emsr2d2]

No. Don't use "deem as".

XXX has been deemed YYY.
XXX has been deemed to be YYY.

 

[tedmc]

Yes, it is the same as "considered".

 

[probus]

Yes, it is the same as "considered".

Perhaps in casual usage, yes, but strictly speaking "deemed" means "conclusively presumed."

"Deemed" is a term much beloved by legislators, because of course lawyers who are being paid will argue anything, regardless of its truth or correctness. 'Deeming" is one of the few ways of shutting them up.

 

[alpacinou]

No. Don't use "deem as".

XXX has been deemed YYY.
XXX has been deemed to be YYY.

Is this correct?

High consumption of energy has been deemed to be one of the main downsides of this new machine.

 

[probus]

Yes, and that is a typical use of deemed.

Marginal note for anyone who likes the works of J R R Tolkien. He made a connection between the noun doom and the verb deem when he had a character say "I deem thy doom". I have not been able to find any other etymological support for that connection.

 

[tedmc]

Apparently, "deemed as" is also common.

 

[probus]

Usage may be common but substandard.
Emsr2d2 is right: avoid deemed as.
