The Corrupt Practices Investigation Bureau (CPIB) is conducting a survey on Singaporeans' perception of corruption here.
It is the second such survey since 2002.
The survey will take place from 20 December to 27 January.
Letters have been sent out to some 1,000 Singaporeans informing them that the CPIB has commissioned a company to conduct house-to-house interviews.
The interviewees would be asked, amongst other questions, what they perceive is the level of corruption in Singapore.
In the 2002 survey, 60 per cent of Singaporeans said they were not willing to report graft.
But in light of the recent corporate scandals, how can Singaporeans be encouraged to come forward?
Dr Habibul Khondker, Associate Professor at National University of Singapore's Sociology Department, said: "I think media can play a bigger role in arousing public interest, in arousing those civic responsibilities in the population, that you have a responsibility that you should not accept things that are not proper. If you see anything improper, you have every right to speak up as these events can be prevented from recurring."
Dr Khondker said that with Singapore being consistently ranked by the transparency index as one of the least corrupt countries, this perception is not likely to change.
He added surveys like the one CPIB has commissioned are what the Berlin-based corruption watchdog relies on for its research.
Thirty questions will be asked in the CPIB survey.
Though the CPIB would not reveal what these questions are, the previous survey had included questions on what Singaporeans thought of the effectiveness of the corruption bureau itself.
Interviewees were also asked to suggest ways to fight corruption. - CNA/ir
The one thing I like about this country: it is absolutely serious about corruption.
