FLASH REPORT: Political Slant Ratings by Show – 1/30 to 2/3

Our latest TV News measurement metrics, targeting individual programs aired by the 3 major broadcast networks (ABC, CBS, and NBC) and the top 3 cable news channels (CNN, Fox News, and MSNBC), is fairly consistent with our previous studies.  As has been our pattern, we have limited our focus shows airing from 5 PM until 11 PM eastern time, Monday through Friday. Because of that, transcript coverage is less than normal since Florida primary coverage preempted several regular programs under study.

It’s worth noting that, particularly in the case of CNN, those special programs garnered Nielsen ratings of roughly twice the average of the programs they replaced (Erin Burnett Outfront & Anderson Cooper 360). For those who wonder why the media is obsessively covering the Republican primaries, your answer lies there.

CHART 1: Slant Rating by Show - January 30 to February 3

As always, content with a numerical rating above zero indicates a Republican slant, with ratings below zero representing a Democratic slant. In this case, however, those shows which are in the +2.0 to -2.0 range are shown in gray, indicating that they are in the “balanced” news category. The one notable exclusion this week is CBS Evening News, but our content coverage for it was exceptionally light. Red remains the color indicator for “slanted” news which favors the Republican party, while slanted content that favors towards the Democratic party is shown in blue. Those interested in the underpinnings of the Mediate Metrics slant rating system should review our January 31st post, or see our primer on Text Analytics Basics at: http://wp.me/p1MQsU-at.

Since our analytical coverage varies by program and date, so does our confidence in the associated show ratings. The exact amount of program coverage is shown in the Table 1 below, but we have graphically indicated depth-of-coverage by way of color shading in Chart 1. For example, the cones representing CBS Evening News, Special Report (Fox), and NBC Nightly News were purposely made lighter to reflect the relatively small transcript coverage for those particular show. We should also note that our version 1.4 classifier did exhibit some anomalies that caused our NBC Nightly News ratings to be disproportionately skewed towards favoring Republicans.

LIBERAL MEDIA BIAS?: Impact Report #2 Provides the Answer(s)

Is there a liberal bias (or as we prefer to call it, political news slant) in the U.S media? It depends largely on which news content you think matters most.

Based on the data we currently have under analysis, early indications are that the leading broadcast and cable new outlets lean towards the Democratic party. With that said, the recently released Pew Research Center News Interest Index indicates that more people are now turning to cable news for information about the 2012 presidential campaign than to other forms of media. Adjusting for their findings yields an entirely different result.

For Impact Report #2,  we have quantified the amount of network slant (aggregate speaker bias plus editorial influence) and combined it with viewership data in order to assess the total “Impact.” In this installment, we have computed the weighted-average Impact Rating for each network during the weeks of January 16th and January 23rd, focused on their evening/weekday news programming. The results are depicted below:

Aggregate Slant Impact: Weekdays - January 16 to 17

Aggregate Slant Impact: Weekdays - January 16 to 27

As in all of our charts, content favoring the Republican party is represented in red (greater than zero), while that which leans towards the Democratic Party is shown in blue (less than zero). We have indicated depth-of-coverage by lightening the base colors as required. For example, the bases representing NBC,CBS, and to a lesser degree Fox News, were purposely made lighter to reflect the limited transcript coverage for those particular networks. Regardless, the basic message depicted in chart above is that the slant rating base is amplified by the number of people viewing the content. The table below shows the numerical analysis supporting the chart:

The Cumulative Slant Ratings  in column 2 were derived from data previously discussed and shown at this site on Wednesday, February 8th. We have also factored in viewership data for the networks and programs under review. As you can see, the cumulative rating for this report — across all networks and programs we are studying —  slightly favors Democrats/Liberals, as indicated by the numbers highlighted in light blue.

If, however, we account for the Pew Research data, which states that 36% of people regularly go to cable networks to learn about Presidential campaigns (and, we presume, national political news in general) versus only 26% turning to national nightly news programs, our cumulative results shift in favor of Republican/conservative interests (as highlighted in light red).

Liberal or conservative media bias? It all depends on whose news one views.

FLASH REPORT: Political Slant by Show – 1/23 to 1/27

Building on our previous post, today we our publishing a separate version of our TV news measurement metrics which focuses on the political slant of individual programs aired by the 3 major broadcast networks (ABC, CBS, and NBC) and the top 3 cable news channels (CNN, Fox News, and MSNBC), based on our enhanced 1.2 classifier. The analysis is focused on shows airing from 5 PM until 11 PM eastern time, Monday through Friday.

CHART 2: Slant Rating by Show - January 23 to 27

We’ve constructed this chart slightly differently than in the past. As always, content with a numerical rating above zero indicates a Republican slant, with ratings below zero representing a Democratic slant. In this case, however, those shows which are in the +2.0 to -2.0 range are shown in gray, indicating that they are in the “balanced” news category. The one notable exclusion this week is NBC Nightly News, but our content coverage for it was exceptionally light. Red remains the color indicator for “slanted” news which favors the Republican party, while slanted content that favors towards the Democratic Party is shown in blue. Those interested in the underpinnings of the Mediate Metrics slant rating system should review our January 31st post, or see our primer on Text Analytics Basics at: http://wp.me/p1MQsU-at.

Since our analytical coverage varies by program and date, so does our confidence in the associated show ratings. The exact amount of program coverage is shown in the Table 2 below, but we have graphically indicated depth-of-coverage by way of color shading in Chart 2. For example, the cones representing CBS Evening News, Special Report (Fox), and NBC Nightly News were purposely made lighter to reflect the relatively small transcript coverage for those particular show.

FLASH REPORT: Media Bias by Network – 1/23 to 1/27

Week 2 of our media bias/slant ratings, based on our new-and-improved version 1.2 classifier,  shows some consistencies and variances from our 1/16 – 20 report of last week.

CHART 1: Slant Ratings by Network - Jan. 23 to 27

NOTE: Net content favoring the Republican Party in Chart 2 is portrayed in red; net content favoring the Democratic Party is shown in blue.

CBS and NBC’s party slant ratings, in comparison to last week’s, actually flipped in both cases. This is not altogether surprising, given that content under analysis for those 2 networks is relatively light, and that the nightly news shows we evaluate for both are “straight” news programs. In contrast, the party alignments of Fox, CNN, ABC, and MSNBC remained consistent, week-to-week.

As noted last Monday, our transcript coverage varies by network, program, and date. Correspondingly, our rating confidence is directly proportional to the amount of transcript text available for classification.The exact amount of coverage per network is shown in the table to the right, but we have graphically indicated depth-of-coverage in Chart 1 by way of color shading. For example, the bars representing the slant ratings for both NBC and CBS were purposely made lighter to reflect the relatively small transcript coverage for those particular networks.

Mediate Metrics’ slant measurement system is currently focused on weekday transcripts from the national nightly news programs on the 3 major broadcast networks (ABC, CBS, and NBC), along with programming aired from 5 PM until 11 PM eastern time on top 3 cable news channels (CNN, Fox, and MSNBC). Compared to last week, coverage under analysis is significantly improved for ABC and NBC, but has decreased for CBS.

For those new to our site, the numerical slant ratings supporting the Chart 1 emanate from a custom text analysis “classifier,” built to extract statements of political slant from TV news transcripts. (For more on the underlying technology, see our post on Text Analytics Basics at: http://wp.me/p1MQsU-at.) We have trained our classifier to interpret political slant quite conservatively, conforming to strict guidelines for the sake of consistency and objectivity. As such, the ratings we present may be perceived as under-reporting the absolute slant of the actual content under review, but the appropriate way to view our ratings is as relative to similar programming.

To properly evaluate editorial content, we have concluded that the Republican presidential primaries and candidates are subject to intense scrutiny. Related news content tends to be disproportionately negative, and often times does not contain a clear inter-party comparison — an element we consider a crucial condition for the proper evaluation of political slant. As such, we have excluded statements about the Republican Presidential primaries and candidates from our slant ratings at this juncture, unless parallel references to the Democratic party are mentioned in parallel.

We’ll publish slant ratings by program for the same January 23 – 27 time period tomorrow.

TV News Political Bias Impact Ratings: January 16 – 20, 2012 (Revised)

Much debate has been devoted to assessing whether there is a liberal or conservative media bias (or as we prefer to call it, political news slant) in the U.S. Most tend to focus on the source of the bias, but our view is somewhat different. At Mediate Metrics, we prefer to quantify the amount of slant (bias plus editorial influence), combined with the quantity of slant recipients, to assess the full impact of media bias.

As presented in our November 15 post, total objectivity and fairness in the news is a virtual impossibility. Still, our hypothesis is that networks will be less biased when their reputation is built upon informing viewers and being an objective resource. In contrast, news outlets which rely on affirming the political preferences of their loyal viewers will have a natural tendency to be more slanted.

Building on our previous 2 posts, we have added a Political Slant “Impact” Rating comparison for January 16th to the 20th, depicted in Chart 3 below:

CHART 3: Slant Impact Rating - January 16 to 20

As in our other charts, content favoring the Republican party is represented in red (numerically positive), while that which leans towards the Democratic Party is shown in blue (numerically negative). We have graphically indicated depth-of-coverage, or lack thereof, by lightening those colors. For example, the bars representing NBC,CBS, and to a lesser degree Fox News and ABC, were purposely made lighter to reflect the relatively small transcript coverage for those particular networks. Regardless of coverage, the basic message depicted in Chart 3 is that the slant “foundation”, depicted at the base of each pyramid, is amplified by the number of people viewing the content. Table 3 below shows the numerical analysis supporting the chart:

TABLE 3: Political Slant Impact Measures - January 16 to 20, 2012

The Composite Weekday Slant Ratings in column 2, along with the number of statements classified in column 3, were derived from data previously discussed and shown here on Tuesday, January 31st. Statement coverage and “Confidence Factors” relate directly to the color shades in Chart 3. Most importantly, we have factored in viewership data for the networks and programs under review. This is where things get interesting, given that:

  • The nightly news programs from the major broadcast networks achieve the highest ratings per program by far, but their impact is mitigated by the fact that they are only broadcasted for 30 minutes a night;
  • By definition, the 3 top cable networks broadcast a continuous line-up of news shows, each of which is 60 minutes long, and representing as much as 420 minutes of programming/network for the nightly time period (5 PM to 11 PM) under consideration.
  • Public service programming, such as the Republican Presidential debates, was purposely omitted from our calculations since it does not reflect the editorial views (slant) of the network-or-program they were broadcast on.

Some compelling notions, however preliminary, can be drawn from this analysis. While the aggregate slant of content delivered during this time period appears to favor Democrats (as depicted in light blue in the “Totals” row), the aggregate impact tilts towards the GOP (as shown in the light red cell, same row).

Admittedly, our classifier and database need further refinement, but we think these initial results are rather intriguing. Still, we’d love to know what you think. Don’t hesitate to leave a comment below, or to send one directly to: barry@mediatemetrics.com.

TV News Political Slant Report by Show: 1/16 – 1/20

Building on our previous post, today we our publishing a separate version of our TV news measurement metrics which focuses on the political slant of individual programs aired by the 3 major broadcast networks (ABC, CBS, and NBC) and the top 3 cable news channels (CNN, Fox News, and MSNBC), for shows aired from 5 PM until 11 PM eastern time, Monday through Friday. As highlighted yesterday, our analytical coverage varies by network, program, and date, but our intention is to augment it over time.

CHART 2: Slant Rating by Program - January 16 to 20, 2012

Content favoring the Republican party in Chart 2 is portrayed in red (numerically positive), while content that slants towards the Democratic Party is shown in blue (numerically negative). Those interested in the underpinnings of the Mediate Metrics slant rating system should review our January 31st post, or see our primer on Text Analytics Basics at: http://wp.me/p1MQsU-at.

Since our analytical coverage varies by network, program, and date, so does the associated confidence factor in our slant ratings. The exact amount of coverage per network is shown in the Table 2 below, but we have graphically indicated depth-of-coverage by way of color shading in Chart 1. For example, the cones representing The Five, Hannity, and On The Record were purposely made lighter to reflect the relatively small transcript coverage for those particular networks. Low transcript coverage likely accounts for certain results that may seem counter-intuitive; we expect those metrics to adapt with volume and time.

TABLE 2: Slant by Program - January 16 to 20, 2012

As mentioned yesterday, we have partitioned statements about the Republican Presidential primaries, since they tend to be disproportionately negative and often lack inter-party comparison, and have largely excluded them from these slant ratings. Similarly, the Republican Presidential debates and other such dedicated program segments have been omitted in their entirety since they do not reflect the political positions of the networks, programs, or contributors under a consideration.

We’ll publish an “impact rating” for the same January 16 – 20 time period tomorrow.

TV News Political Slant Report by Network: 1/16 – 1/20

Welcome to the Mediate Metrics inaugural TV news political slant measurement report, based on our version 1.0 text classifier.

To our knowledge, this is the first objective TV news slant rating service ever published. Slant, by our definition, is news containing an embedded statement of bias (opinion) OR an element of editorial influence (factual content that reflects positively or negatively on a particular U.S. political party). This initial report focuses specifically on evaluating  slant contained in the weekday transcripts of  the national nightly news programs on the 3 major broadcast networks (ABC, CBS, and NBC) , as well as programming aired from 5 PM until 11 PM eastern time on top 3 cable news channels (CNN, Fox, and MSNBC). At this stage, analytical coverage varies by network, program, and date, but our intention is to fill in the blanks over time.

CHART 1: Slant by Network - January 16 to January 20, 2012

In keeping with U.S. political tradition, content favoring the Republican party in Chart 1 is portrayed in red (positive numbers), while content that tilts towards the Democratic Party is shown in blue (negative numbers)

To grossly over-simplify, the numerical slant ratings supporting the Chart 1 emanate from a custom text analysis “classifier,” built to extract statements of political slant from TV news transcripts. (For more on the underlying technology, see our post on Text Analytics Basics at http://wp.me/p1MQsU-at.) We have trained our classifier to interpret slant quite conservatively, conforming to strict guidelines for the sake of consistency and objectivity. As such, the ratings we present may be perceived as under-reporting the absolute slant of the actual content under review, but the appropriate way to view our ratings is as relative to similar programming.

As mentioned, our analytical coverage varies by network, program, and date. Correspondingly, our rating confidence is directly proportional to the amount of transcript text available for classification.The exact amount of coverage per network is shown in the table to the right, but we have graphically indicated depth-of-coverage in Chart 1 by way of color shading. For example, the bars representing the slant ratings for both NBC and CBS were purposely made lighter to reflect the relatively small transcript coverage for those particular networks.

During development, we determined that the Republican presidential primaries are an enterprise for which scrutiny is a normal-and-valuable part of the vetting process.  Related news content, however, tends to be disproportionately negative, and often times does not contain a clear inter-party comparison — an element we view as a crucial condition for the evaluation of political slant. With those factors mind, we have partitioned statements about the Republican Presidential primaries, and have excluded them from most slant ratings at this juncture. Similarly, the Republican Presidential debates and other such dedicated program segments have been excluded in their entirety from classification since they do not reflect the political positions of the networks, programs, or contributors under a consideration.

We’ll publish slant ratings by program for the same January 16 – 20 time period tomorrow.
