A cliché about optimism and pessimism is that a pessimist
says the glass is half empty, while an optimist says the glass is half full. There even
is a
Wikipedia page.
There are other more creative
replies. A physicist says the glass really is half-filled with water and
half-filled with air. An engineer says the glass is twice as big as it needs to
be. A bartender says for $2 I can refill the glass with orange juice, or for $5
I can add a fifth of a glass of vodka, and make it into
Screwdrivers. (That’s
a specific version of a
Tom Peters quote - that the real question instead should
be how do I fill the glass?). If the glass scares you half to death, then you
have
glassophobia.
Ratbert: A pessimist says the glass is half empty. An
optimist says it’s half full.
Dilbert: Did you put your lips on my glass again?
Ratbert: And the engineer says…
Dilbert: It’s a good thing I put half of my water in a
redundant glass.
Pointy-haired Boss: A pessimist says the glass is half
empty. An optimist says it is half full.
Dilbert: The engineer says the glass is too big.
Pointy-haired Boss: The manager says the engineer should
shut his pie hole.
There was an article by Diana Booher on pages 12 and 13 of
the
February 2010 issue of
Toastmaster magazine titled
The Link Between
Language and Leaders which said:
“As a presenter and leader, you may be called on to deliver
bad news. If your audience sees the glass as half empty, you have every right –
even an obligation – to help them see it as half full.”
I looked on
Pubmed and found a pair of articles from 2011 in
the
Canadian Veterinary Journal by Myrna Milani on
Half-empty and half-full
communication – one in October about
the client and one in December about
the
practitioner. There also is a definitive
27-page article with 320 references by David
Hecht in the September 2013 issue of
Experimental Neurobiology about
The neural
basis of optimism and pessimism.
Update on September 19, 2018
Fifteen years ago there was
a magazine article by Craig R. M.
McKenzie and Jonathan D. Nelson titled
What a speaker’s choice of frame
reveals: reference points, frame selection, and framing effects that appeared
in the
Psychonomic Bulletin and Review for 2003, on pages 596 to 602, vol. 10 no.
3. Their abstract began [percentages added by me]:
“Framing effects are well established: Listeners’
preferences depend on how outcomes are described to them, or framed. Less well
understood is what determines how speakers choose frames. Two experiments
revealed that reference points systematically influenced speakers’ choices
between logically equivalent frames. For example, [88% of] speakers tended to
describe a 4-ounce cup filled to the 2-ounce line as half full if it was previously empty but [only 31% described it as
half full or instead 69%] described it as half
empty if it was previously full.”
They also looked at glasses one-quarter or three-quarters
full, with the results shown above.
