Enrichment programs and public perception

[urbpan]

I have a couple questions which may seem terribly cynical, but they are on my mind and I'd like to get some opinions on them:

How important is public perception to an enrichment program: How much of the content of the enrichment program exists to improve public relations and increase the public image of the zoo (whether or not the enrichment method is an obvious one)? If some of the content of the enrichment program exists to increase the public image of the zoo, how forthright should the zoo be about this side-benefit of the enrichment program?
