Τέλος στα 'Black Boxes'

Το βασικότερο πρόβλημα με τις μετρήσεις, κάθε είδους μετρήσεις, είναι το αδιαφανές της μεθόδου και η μη πρόσβαση στα παραγόμενα δεδομένα.

Για παράδειγμα η AGB Nielsen με περηφάνια δηλώνει στη σελίδα της για τη μεθοδολογία ότι:

"the "heart" of the AGB system is the production software POLLUX. POLLUX performs the collection, control, processing, validation, weighting and final production of the data and the quality control tables used every day. Media Services develops and supports POLLUX, which is based on the concept of the "black box". This means that only AGB Media Services has access to the source codes and none of the sister companies, a fact which ensures the operation of the system in a uniform, transparent and reliable manner in all countries of the Group.Transparency of all procedures is a major characteristic of POLLUX. This means that one may look back in time and examine the whole production process for any given day. The auditors of the system thus have full access to any information for any period."

Black box και transparency στην ίδια πρόταση! Δεν ξέρω αν τελικά αυτό το δεύτερο post είναι πιο αστείο από το πρώτο!

Για αυτό πιστεύω ότι χρειαζόμαστε μία μεθοδολογία αντίστοιχη με αυτή του open source στον προγραμματισμό. Περισσοτέρα υπάρχουν μπορεί να διαβάσει κανείς στο:

The Methods and Accuracy of Polling -Toward an Open- Source Methodology What We Can Learn from the Blogosphere

Υπάρχει και ένα άλλο σοβαρό ζήτημα που έχει να κάνει με τον πραγματικό στόχο της έρευνας (μετρά ή μήπως τελικά ενημερώνει/προπαγανδίζει πλαγίως;). Περισσότερα σε επόμενο post.

The Perfect Balanced Sample

Sir Humphrey: "You know what happens: nice young lady comes up to you. Obviously you want to create a good impression, you don't want to look a fool, do you? So she starts asking you some questions: Mr. Woolley, are you worried about the number of young people without jobs?"

Bernard Woolley: "Yes"

Sir Humphrey: "Are you worried about the rise in crime among teenagers?"

Bernard Woolley: "Yes"

Sir Humphrey: "Do you think there is a lack of discipline in our Comprehensive schools?"

Bernard Woolley: "Yes"

Sir Humphrey: "Do you think young people welcome some authority and leadership in their lives?"

Bernard Woolley: "Yes"

Sir Humphrey: "Do you think they respond to a challenge?"

Bernard Woolley: "Yes"

Sir Humphrey: "Would you be in favour of reintroducing National Service?"

Bernard Woolley: "Oh...well, I suppose I might be."

Sir Humphrey: "Yes or no?"

Bernard Woolley: "Yes"

Sir Humphrey: "Of course you would, Bernard. After all you told you can't say no to that. So they don't mention the first five questions and they publish the last one."

Bernard Woolley: "Is that really what they do?"

Sir Humphrey: "Well, not the reputable ones no, but there aren't many of those. So alternatively the young lady can get the opposite result."

Bernard Woolley: "How?"

Sir Humphrey: "Mr. Woolley, are you worried about the danger of war?"

Bernard Woolley: "Yes"

Sir Humphrey: "Are you worried about the growth of armaments?"

Bernard Woolley: "Yes"

Sir Humphrey: "Do you think there is a danger in giving young people guns and teaching them how to kill?"

Bernard Woolley: "Yes"

Sir Humphrey: "Do you think it is wrong to force people to take up arms against their will?"

Bernard Woolley: "Yes"

Sir Humphrey: "Would you oppose the reintroduction of National Service?"

Bernard Woolley: "Yes"

Sir Humphrey: "There you are, you see Bernard. The perfect balanced sample."
